Branch: i30_pythongeometry | Intent: Create module of native Python functions to
	replace numpy functions used in eppy geometry modules
Commit Intent: Create a test function for the cross product function in py_numeric.py
---------------------------------------------------------------------------------------
*/eppy/geometry/py_numeric.py
-Added a simple multiplication statement for the two function arguments in cross()...
-Added a return statement to provide the product as a result of calling the function...

*eppy/tests/geometry_tests/test_py_numeric.py
-Added a simple assertion statement intended to confirm the test function correctly
 referencing the module function

**py.test passes!

Commit Intent: Expand on the basic test function for the cross product function in
	py_numeric.py
---------------------------------------------------------------------------------------
*/eppy/geometry/py_numeric.py
-Implemented a vector cross product, assuming the cross() function's input arguments are
 3-dimentional vectors...

*eppy/tests/geometry_tests/test_py_numeric.py
-Changed test data from simple numerical values to vectors based on example from numpy's
 'numeric.py' module's cross() function docstring...

-Added a print statement to see what the output of the function call is to compare with
 assertion statement
