-	 * URI syntax, please see RFC 3986 at http://www.ietf.org/rfc/rfc3986.txt

-	 * or do a web search for "rfc 3986".

-	 * 

-	 * <p>The most important aspect of URI's to understand is that URI's

-	 * and URL's are not strings.  URI's are complex data structures that

-	 * encapsulate many pieces of information.  The string version of a

-	 * URI is the serialized representation of that data structure.  This

-	 * string serialization is used to provide a human readable

-	 * representation and a means to transport the data over the network

-	 * where it can then be parsed back into its' component parts.</p>

-	 * 

-	 * <p>URI's fall into one of three categories:

-	 * <ul>

-	 *  <li>&lt;scheme&gt;:&lt;scheme-specific-part&gt;#&lt;fragment&gt;		(non-hierarchical)</li>

-	 *  <li>&lt;scheme&gt;:<authority&gt;&lt;path&gt;?&lt;query&gt;#&lt;fragment&gt;	(hierarchical)</li>

-	 *  <li>&lt;path&gt;?&lt;query&gt;#&lt;fragment&gt;						(relative hierarchical)</li>

-	 * <p>The query and fragment parts are optional.</p>

-	 * 

-	 * <p>This class supports both non-hierarchical and hierarchical URI's</p>

-	 * 

-	 * <p>This class is intended to be used "as-is" for the vast majority

-	 * of common URI's.  However, if your application requires a custom

-	 * URI syntax (e.g. custom query syntax or special handling of

-	 * non-hierarchical URI's), this class can be fully subclassed.  If you

-	 * intended to subclass URI, please see the source code for complete

-		 * Given a URI in string format, parse that sucker into its basic

-		 * components and assign them to this object.  A URI is of the form:

-		 *    <scheme>:<authority><path>?<query>#<fragment>

-		 *

-		 * For simplicity, we parse the URI in the following order:

-		 * 		

-		 *		1. Fragment (anchors)

-		 * 		2. Query	(CGI stuff)

-		 * 		3. Scheme	("http")

-		 * 		4. Authority (host name)

-		 * 		5. Username/Password (if any)

-		 * 		6. Port		(server port if any)

-		 *		7. Path		(/homepages/mypage.html)

-		 *

-		 * The reason for this order is to minimize any parsing ambiguities.

-		 * Fragments and queries can contain almost anything (they are parts

-		 * that can contain custom data with their own syntax).  Parsing

-		 * them out first removes a large chance of parsing errors.  This

-		 * method expects well formed URI's, but performing the parse in

-		 * this order makes us a little more tolerant of user error.

-		 * 

-		 * REGEXP

-		 * Why doesn't this use regular expressions to parse the URI?  We

-		 * have found that in a real world scenario, URI's are not always

-		 * well formed.  Sometimes characters that should have been escaped

-		 * are not, and those situations would break a regexp pattern.  This

-		 * function attempts to be smart about what it is parsing based on

-		 * location of characters relative to eachother.  This function has

-		 * been proven through real-world use to parse the vast majority

-		 * of URI's correctly.

-		 *

-		 * NOTE

-		 * It is assumed that the string in URI form is escaped.  This function

-		 * does not escape anything.  If you constructed the URI string by

-		 * hand, and used this to parse in the URI and still need it escaped,

-		 * call forceEscape() on your URI object.

-		 *

-		 * Parsing Assumptions

-		 * This routine assumes that the URI being passed is well formed.

-		 * Passing things like local paths, malformed URI's, and the such

-		 * will result in parsing errors.  This function can handle

-		 * 	 - absolute hierarchical (e.g. "http://something.com/index.html),

-		 *   - relative hierarchical (e.g. "../images/flower.gif"), or

-		 *   - non-hierarchical URIs (e.g. "mailto:jsmith@fungoo.com").

-		 * 

-		 * Anything else will probably result in a parsing error, or a bogus

-		 * URI object.

-		 * 

-		 * Note that non-hierarchical URIs *MUST* have a scheme, otherwise

-		 * they will be mistaken for relative URI's.

-		 * 

-		 * If you are not sure what is being passed to you (like manually

-		 * entered text from UI), you can construct a blank URI object and

+	 * representation and a means to transport the data over the network
+	 * where it can then be parsed back into its' component parts.</p>
+	 * 
+	 * <p>URI's fall into one of three categories:
+	 * <ul>
+	 *  <li>&lt;scheme&gt;:&lt;scheme-specific-part&gt;#&lt;fragment&gt;		(non-hierarchical)</li>
+	 *  <li>&lt;scheme&gt;:<authority&gt;&lt;path&gt;?&lt;query&gt;#&lt;fragment&gt;	(hierarchical)</li>

+	 * of common URI's.  However, if your application requires a custom
+	 * URI syntax (e.g. custom query syntax or special handling of
+	 * non-hierarchical URI's), this class can be fully subclassed.  If you

+		 * Given a URI in string format, parse that sucker into its basic
+		 * components and assign them to this object.  A URI is of the form:
+		 *    <scheme>:<authority><path>?<query>#<fragment>
+		 *
+		 * For simplicity, we parse the URI in the following order:
+		 * 		
+		 *		1. Fragment (anchors)
+		 * 		2. Query	(CGI stuff)
+		 * 		3. Scheme	("http")
+		 * 		4. Authority (host name)
+		 * 		5. Username/Password (if any)
+		 * 		6. Port		(server port if any)
+		 *		7. Path		(/homepages/mypage.html)
+		 *
+		 * The reason for this order is to minimize any parsing ambiguities.
+		 * Fragments and queries can contain almost anything (they are parts
+		 * that can contain custom data with their own syntax).  Parsing
+		 * them out first removes a large chance of parsing errors.  This
+		 * method expects well formed URI's, but performing the parse in
+		 * this order makes us a little more tolerant of user error.
+		 * 
+		 * REGEXP
+		 * Why doesn't this use regular expressions to parse the URI?  We
+		 * have found that in a real world scenario, URI's are not always
+		 * well formed.  Sometimes characters that should have been escaped
+		 * are not, and those situations would break a regexp pattern.  This
+		 * function attempts to be smart about what it is parsing based on
+		 * location of characters relative to eachother.  This function has
+		 * been proven through real-world use to parse the vast majority
+		 * of URI's correctly.
+		 *
+		 * NOTE
+		 * It is assumed that the string in URI form is escaped.  This function
+		 * does not escape anything.  If you constructed the URI string by
+		 * hand, and used this to parse in the URI and still need it escaped,
+		 * call forceEscape() on your URI object.
+		 *
+		 * Parsing Assumptions
+		 * This routine assumes that the URI being passed is well formed.
+		 * Passing things like local paths, malformed URI's, and the such
+		 * will result in parsing errors.  This function can handle
+		 * 	 - absolute hierarchical (e.g. "http://something.com/index.html),
+		 *   - relative hierarchical (e.g. "../images/flower.gif"), or
+		 *   - non-hierarchical URIs (e.g. "mailto:jsmith@fungoo.com").
+		 * 
+		 * Anything else will probably result in a parsing error, or a bogus
+		 * URI object.
+		 * 
+		 * Note that non-hierarchical URIs *MUST* have a scheme, otherwise
+		 * they will be mistaken for relative URI's.
+		 * 
+		 * If you are not sure what is being passed to you (like manually
+		 * entered text from UI), you can construct a blank URI object and
+		 * call unknownToURI() passing in the unknown string.
