This is a custom shindig library that has not yet been submitted =
for=0A=
* standardization. It is designed to make developing of features for the=0A=
* opensocial / gadgets platforms easier and is intended as a =
supplemental=0A=
* tool to Shindig's standardized feature loading mechanism.=0A=
*=0A=
* Usage:=0A=
* First, you must register a component that needs configuration:=0A=
*
=0A=
* var config =3D {=0A=
* name : gadgets.config.NonEmptyStringValidator,=0A=
* url : new gadgets.config.RegExValidator(/.+%mySpecialValue%.+/)=0A=
* };=0A=
* gadgets.config.register("my-feature", config, myCallback);=0A=
* =0A=
*=0A=
* This will register a component named "my-feature" that expects =
input config=0A=
* containing a "name" field with a value that is a non-empty string, =
and a=0A=
* "url" field with a value that matches the given regular expression.=0A=
*=0A=
*
When gadgets.config.init is invoked by the container, it will =
automatically=0A=
* validate your registered configuration and will throw an exception if=0A=
* the provided configuration does not match what was required.=0A=
*=0A=
*
Your callback will be invoked by passing all configuration data =
passed to=0A=
* gadgets.config.init, which allows you to optionally inspect =
configuration=0A=
* from other features, if present.=0A=
*=0A=
*
Note that the container may optionally bypass configuration =
validation for=0A=
* performance reasons. This does not mean that you should duplicate =
validation=0A=
* code, it simply means that validation will likely only be performed =
in debug=0A=
* builds, and you should assume that production builds always have valid=0A=
* configuration.=0A=

* For Internet Explorer before version 8, the security model allows =
anyone=0A=
* parent to set the value of the "opener" property on another window,=0A=
* with only the receiving window able to read it.=0A=
* This method is dubbed "Native IE XDC" (NIX).=0A=
*=0A=
* This method works by placing a handler object in the "opener" property=0A=
* of a gadget when the container sets up the authentication information=0A=
* for that gadget (by calling setAuthToken(...)). At that point, a NIX=0A=
* wrapper is created and placed into the gadget by calling=0A=
* theframe.contentWindow.opener =3D wrapper. Note that as a result, NIX =
can=0A=
* only be used by a container to call a particular gadget *after* that=0A=
* gadget has called the container at least once via NIX.=0A=
*=0A=
* The NIX wrappers in this RPC implementation are instances of a =
VBScript=0A=
* class that is created when this implementation loads. The reason for=0A=
* using a VBScript class stems from the fact that any object can be =
passed=0A=
* into the opener property.=0A=
* While this is a good thing, as it lets us pass functions and setup a =
true=0A=
* bidirectional channel via callbacks, it opens a potential security =
hole=0A=
* by which the other page can get ahold of the "window" or "document"=0A=
* objects in the parent page and in turn wreak havok. This is due to the=0A=
* fact that any JS object useful for establishing such a bidirectional=0A=
* channel (such as a function) can be used to access a function=0A=
* (eg. obj.toString, or a function itself) created in a specific =
context,=0A=
* in particular the global context of the sender. Suppose container=0A=
* domain C passes object obj to gadget on domain G. Then the gadget can=0A=
* access C's global context using:=0A=
* var parentWindow =3D (new obj.toString.constructor("return =
window;"))();=0A=
* Nulling out all of obj's properties doesn't fix this, since IE =
helpfully=0A=
* restores them to their original values if you do something like:=0A=
* delete obj.toString; delete obj.toString;=0A=
* Thus, we wrap the necessary functions and information inside a =
VBScript=0A=
* object. VBScript objects in IE, like DOM objects, are in fact COM=0A=
* wrappers when used in JavaScript, so we can safely pass them around=0A=
* without worrying about a breach of context while at the same time=0A=
* allowing them to act as a pass-through mechanism for information=0A=
* and function calls. The implementation details of this VBScript =
wrapper=0A=

* @fileoverview Pure JS code for processing Uris.=0A=
*=0A=
* Unlike Java Shindig and other code, these Uris are mutable. While=0A=

* by passing around a Uri versus a UriBuilder in an untyped language=0A=
* is too great.=0A=
*=0A=
* The class only implements core methods associated with Uris -=0A=
* essentially the minimum required for various helper routines. Lazy =
evalution=0A=
* of query and fragment params is chosen to avoid undue performance hit.=0A=
* Further, only set operations are provided for query/fragment params,=0A=
* in order to keep the API relatively small, yet sufficiently flexible. =
Values set to=0A=
* null are equivalent to being removed, for instance.=0A=
* =0A=
* Limitations include, but are not limited to:=0A=
* + Multiple params with the same key not supported via set APIs.=0A=
* + Full RPC-compliant parsing not supported. A "highly useful" subset =
is impl'd.=0A=
* + Helper methods are all provided in the shindig.uri.full feature.=0A=
* + Query and fragment do not contain their preceding ? and # chars.=0A=
*=0A=
* Example usage:=0A=
* var uri =3D shindig.uri("http://www.apache.org");=0A=
