/**
 * NullAuthenticationProvider
 * 
 * An implementation of the iApplicationAuthenticationProvider interface with
 * no external dependencies (and also limited functionality) intended to be used
 * as a development tool for quickly testing and debugging applications without
 * having to set up detailed auth&auth dependencies. 
 * 
 * This class utilizes the PHP Session construct for storing a provided username.
 * Any username / password combination is treated as valid.
