/**
*
* This class encapsulates how an object can be converted to a URI string. There
* are three basic ways to perform the transformation:
*
*
* - adding a @URITemplate("your-uri-template") to an object
*
- having an object extend URIable and have the object perform custom logic
*
- registering a custom URIResolver
