[vtk-developers] Information Key documentation

I'd recommend that we document the keys using doxygen's "group"
support (@defgroup, @ingroup). That enables doxygen to generate a
"module" page for the entries in a particular group while the entries
themselves can be defined in different files. We use that in ParaView:
http://www.paraview.org/ParaView3/Doc/Nightly/html/modules.html, for example.

This will avoid the need to document the entries at one central
location in the source, while still providing a central access page
for the generated documentation.

We can even create different groups for the keys based on their role
e.g. keys used in pipeline requests, keys used for meta-data, etc.
