/**
 * bbPress BuddyPress Component Class
 *
 * bbPress and BuddyPress are designed to connect together seamlessly and
 * invisibly, and this is the hunk of code necessary to make that happen.
 *
 * The code in this BuddyPress Extension does some pretty complicated stuff,
 * far outside the realm of the simplicity bbPress is traditionally known for.
 *
 * While the rest of bbPress serves as an example of how to write pretty, simple
 * code, what's in these files is pure madness. It should not be used as an
 * example of anything other than successfully juggling chainsaws and puppy-dogs.
