HL_NPOESS

Maintenance: 

While working on the NPP aggregation tool nagg we came accross several problems.
The changes below are probably not the best solution, but we need to release nagg tomorrow
and this was the easiest and the simplest way to resolve the problems.

1. Since HL library requires F2003 compiler, we couldn't build wiht the HDF5 libraries installed on our systmes.
   I decided to provide a default Makefile that just builds C library only, and added Makefile-F03 that builds
   both C and Fortran libraries.
2. Updated instructions accordingly in README.txt file
3. Updated version to 1.1.1
4. Inluded hdf5.h into h5hl_region.h to avoid complexity in the nagg configure.

Platforms tested: koala; more testing will follow.
