Detailed Description

template<class X>
class code::Factory< X >

This class "introduces" new subclasses that have been created to the parent class.

This is necessary for clients of your class to obtain your class by invoking getReader, getFormatter, etc.

A subclass will have to be introduced to the rest of the system before it can interoperate with existing applications because all the existing applications use only getReader, getFormatter, etc. and can usually be extended by adding a std::string to their configuration.

Note that all the std::strings that get passed into Introducer are case-insensitive. "VIL" is the same as "vil" or "viL".
