Branch: i30_pythongeometry | Intent: Create module of native Python functions to
	replace numpy functions used in eppy geometry modules
Commit Intent: Modify test_py_numeric.py to account for vectors of various sizes
---------------------------------------------------------------------------------------
*eppy/geometry/surface.py
-Renamed the first test function to distinguish from subsequent test functions...
-Replaced tab with spaces in line 27 to comply with pep8...
-Copied first test below it and modified to test the cross product of mixed dimentional
 vectors...

---------------------------------------------------------------------------------------
*eppy/geometry/surface.py
-Added two statements to find the length of each vector passed to the function as a
 parameter...
-Inserted an IF statement around the calculation code to exectute under the intended
 vector dimension only
