CONFIGURATION (for the developer): 

Define the names of functions and classes used by this plugin so we can test 
for conflicts prior to loading the plugin and message the WP admins if there are
any conflicts.

$function_names_used -- add any functions declared by this plugin in the 
	main namespace (e.g. utility functions or theme functions).

$class_names_used -- add any class names that are declared by this plugin.

Warning: the text-domain for the __() localization functions is hardcoded.
