Main Getting Started page and the three HDF Resources have pages. (#2092)

HDFView is still under construction, but mostly there.

Merge the Fortran doxygen changes from develop PR, updated RM index.
Adjusted references to UG and created some TODOs for missing UG modules
Some may just need a reference back to a section of the user guide. Made
some Fortran doxygen changes for overall consistency.
