Fix class detection macro

Weird whitespace confused the regex. The old regex failed to catch:

    class FOO_EXPORTS  vtkFoo : public vtkObject

because of the double space.

This program takes a list of module files and creates a
(possibly disjoint) directed graph of the modules and their
dependencies. Arrows on the directed graph point to the
dependent module.

Tested on Windows/Linux for various lists of modules. Additionally
tested on all the vtk modules by replacing the line:
graph = GenerateGraph(moduleList, moduleDepencencies, moduleTreeDepth)
with
graph = GenerateGraph(moduleDepencenciesmoduleList, moduleDepencencies, moduleTreeDepth)
