Detailed Description

template<class Type>
class AlignSetup< Type >

A helper class to hold objects used by modules in alignment.

AlignSetup has a template parameter to specify the type of objects it holds. Objects are stored in a map<string, Type>. Users put/get an object by passing its name through the static methods put()/get(). It returns 0 if the name is not found on get(). It throws an exception if an object of the same name exists on put().
