Noel Eck 2f78d9f62b 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
