MooseX::MarkAsMethods allows one to easily mark certain functions as Moose
methods. This will allow other packages such as the namespace::autoclean
manpage to operate without blowing away your overloads. After using
MooseX::MarkAsMethods your overloads will be recognized by the Class::MOP
manpage as being methods, and class extension as well as composition from
roles with overloads will "just work".

By default we check for overloads, and mark those functions as methods.

If 'autoclean => 1' is passed to import on use'ing this module, we will
invoke namespace::autoclean to clear out non-methods.
