Provide a utility program that detects and reports system variables that affect VAPOR.

[shaomeng]

Sometimes system variables can affect behaviors of VAPOR. These variables can be OS (Linux, Windows, etc.), software libraries (ZFP, HDF5, drivers) or even hardware (Graphics card, network). It'd be useful to have a standalone program that detects these variables, and reports back how VAPOR will be affected by these variables.

A few candidate variables are:

1. Whether ZFP (or other compression) is supported
2. Whether OpenMP is supported
3. Whether GPU acceleration is supported on tricky grids.
4. If Python API is available or not.
5. (any other ideas?)

This functionality can be tagged along with the current vaporversion utility program.
