Add cmake build to release branch (#30)

## DESCRIPTION OF CHANGES: 
This is a subset of the changes that were added to develop with PR #27. This commit adds cmake capabilities, but does not maintain back-compatibility with the older build system.

To build, have the necessary modules loaded and run:

```
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=<prefix>
make
```

The docs/ directory contains README files with instructions for specific platforms/compilers

## TESTS CONDUCTED: 
 - **Cheyenne**: Build and end-to-end test ("DOT_OR_USCORE" test case) was successful on Cheyenne with intel
 - **Hera**: Build and end-to-end test ("DOT_OR_USCORE" test case) was successful
