/**
* Autoload a Class

* (AbstractLoader, GenericInterface, Module, Path, etc.) has been
* constructed for this function to occur.
*
* This function first establishes a base path either from a predefined
* constant (presumably from the bootstrap), the default path set in the
* autoloader (this is obviously overwritten by the constant), or, in the
* case that these are not specified, two folders up ( /library/ ).
*
* Then it parses the class string with the appropriate delimiters.
*
* It moves on to parse through the modules, constructing a path,
* by concatenating relative paths and replacing with absolute paths.
*
* If path remnants are left over, it constructs a NEW path (losing
* extensions but not prefixes). This is important, if you want
* extensions the path object must be in the terminating module.
*
* It then checks file existence with prefixes, and then it processes
* through independent paths (like an include path string)
*
* NOTE: This function uses require_once
*
* @param string $class The fully qualified class name to load
*
