CRM_Core_Resources
class CRM_Core_Resources
This class facilitates the loading of resources such as JavaScript files and CSS files.
Any URLs generated for resources may include a 'cache-code'. By resetting the cache-code, one may force clients to re-download resource files (regardless of any HTTP caching rules).
TODO: This is currently a thin wrapper over CRM_Core_Region. We should incorporte services for aggregation, minimization, etc.
