Detailed Description

Abstract base class from which all _option<T> objects inherit.

This provides the abstract interface to an _option object. Every parameter that will be accessed via a command line option must have:

• a name to identify it,
• a string identifying its type, for the user's convenience,
• a way of setting its value from an input string,
• a way of writing its value to an output string.
