Detailed Description

template<class T>
class Selector< T >

Functor that operates on <T>

Implements a string-indexed bit_vector.

class template that implements an interface to Selector utilities. This allows the user to access individual cuts based on a string index. The user can then turn individual cuts on and off at will.
