/**
* Class: OpenLayers.Projection
* Class for coordinate transforms between coordinate systems.
* Depends on the proj4js library. If proj4js is not available,
* then this is just an empty stub.
* Namespace: OpenLayers.Projection
* Methods for coordinate transforms between coordinate systems. By default,
* OpenLayers ships with the ability to transform coordinates between
* geographic (EPSG:4326) and web or spherical mercator (EPSG:900913 et al.)
* coordinate reference systems. See the <transform> method for details
* on usage.
*
* Additional transforms may be added by using the <proj4js at http://proj4js.org/>
* library. If the proj4js library is included, the <transform> method
* will work between any two coordinate reference systems with proj4js
* definitions.
*
* If the proj4js library is not included, or if you wish to allow transforms
* between arbitrary coordinate reference systems, use the <addTransform>
* method to register a custom transform method.
