The prompt help system now uses bold text for the title line and all subtitles.

The subtitle underlines are now not used, but the ability to underline is retained.

The relax prompt help system is now being passed through pydoc.pager to page the text.

This system will be used by the auto-generated user functions.

The documentation for the auto-generated user functions is now being created.

This is stored in the __relax_help__ string, and mimics the old system, reusing many of the base
functions. All the user function data required for the prompt interface is now being passed in to
the object.

Renamed the private _args variable to the non-private kargs.

The user function object now has a __repr__ method to give better feedback to the user.

Primitive auto-generation of the user functions.

This simply creates an object for the user function, but it is not callable yet or uses any of the
user function data.

Modified the pipe user function class description.

The __description__ attribute from the old help system is now supported in the auto-generated classes.

The new auto-generated user function classes now fit into the prompt help system.

Documented the prompt-based help system _Helper.__call__() method.
