/**
* This class proivdes various helper functions for locating extensions
* data. It's designed for compatibility with pre-existing functions from
* CRM_Core_Extensions.
*
* Most of these helper functions originate with the first major iteration
* of extensions -- a time when every extension had one eponymous PHP class,
* when there was no PHP class-loader, and when there was special-case logic
* sprinkled around to handle loading of "extension classes".
*
* With module-extensions (Civi 4.2+), there are no eponymous classes --
* instead, module-extensions follow the same class-naming and class-loading
* practices as core (and don't require special-case logic for class
* loading). Consequently, the helpers in here aren't much used with
* module-extensions.
