python_examples: Reformatted, self-checking, executable
* Moved body of each python example to main. This allows for basic
load module testing for CI
* General cleanup of python modules (crlf/tabs/prints/etc)
* Chmod'ed to 755 to allow running examples without specifying the
python interpreter
* Added ctest for loading python2/3 modules
* Added jniclasscode pragma for java swig interface files.
* Updated check_examplenames.py module to check all languages vs. a
cxx example name
* Added tests for checking python module and test loading
* Added 'make test' to travis-ci run (run ctests)
* Print a more meaningful message when not building cxx docs into
python modules
* Updated check_clean.py to only check java wrapper files
* ENABLED ctests for UPM
* Deleted using_carrays.py python example - this is covered by other
examples
