* Grouped UPM python modules into upm directory, for example:
/usr/local/lib/python2.7/dist-packages/upm
* Updated UPM example import statements
* Removed unused RPATH statements from UPM src CMakeLists.txt,
currently build collateral contains an explicit RPATH which
is stripped from the install collateral.
* Converted python examples to work on both python2 AND python3
* Added ctest for loading examples w/python3
* Removed returns from swig macros
* UPM python module use will change...
Before:
import pyupm_dfrph
After:
from upm import pyupm_dfrph
or
import upm.pyupm_dfrph
etc...
* This commit fixes #468
