This module provides all of the same functionality of WWW::Mechanize, but 
adds support for plugins using Module::Pluggable; this means that any 
module named WWW::Mechanize::Plugin::whatever... will be found and loaded 
when WWW::Mechanize::Pluggable is loaded.

Big deal, you say. Well, it becomes a big deal in conjunction with 
WWW::Mechanize::Pluggable's other feature: plugin hooks. When plugins are 
loaded, their import() methods can call WWW::Mechanize::Pluggable's 
prehook and posthook methods. These methods add callbacks to the plugin 
code in WWW::Mechanize::Pluggable's methods. These callbacks can act 
before a method or after it, and have to option of short-circuiting the 
call to the WWW::Mechanize::Pluggable method altogether.

These methods receive whatever parameters the WWW::Mechanize::Pluggable 
methods received, plus a reference to the actvive Mech object.

All other extensions to WWW::Mechanize::Pluggable are handled by the 
plugins.
