Enhance WhatModulesVTK.py

The python script accepts either a file as the second
parameter or a directory.
If a directory is passed to the program it is
recursively searched for all files that contain includes.

The script has been enhanced to parse the module.cmake files
in order to calculate, in addition the set of all modules
referenced in the files, the following extra sets:

1) A minimal set of modules that need to be referenced.
2) A set of modules where all the dependencies are chased down.

Add missing IsPODPointer check, for overload resolution.

The vtkWrapPython_ArgCheckString() method was not adding the necessary
arg check characters for PODPointer-type parameters.  This can potentially
result in incorrect method overload resolution.

DOC: Added documentation to CMake API functions

Improve the documentation of the CMake API, making it clearer what
the expected behavior is, and how the macros/functions should be
used. Also made some very minor whitespace changes in one or two
places for consistency with the rest of the file.
