 * NextGEN Gallery is built on top of the Photocrati Pope Framework:

 * Pope constructs applications by assembling modules.

 * The Bootstrapper. This class performs the following:
 * 1) Loads the Pope Framework
 * 2) Adds a path to the C_Component_Registry instance to search for products
 * 3) Loads all found Products. A Product is a collection of modules with some
 * additional meta data. A Product is responsible for loading any modules it
 * requires.
 * 4) Once all Products (and their associated modules) have been loaded (or in
 * otherwords, "included"), the modules are initialized.
