wrote tests for all window functions (functions starting with "w")
Merge pull request #16 from Apollo117/w_tests

window function tests written
wrote tests for some functions starting with 'r', and it looks like I will need to find a way to improve the existing stypes structs, for example getting an array from a plane struct to be a python list, a new feature to work on...

Improved planes so that the attributes are returned as python types, like the normal which is returned now as a list if "plane.normal" is called. The method enableing this will soon be propogated to other cytpes structs used.

improved ellipse struct to reflect lessons learned from the plane PR, wrote tests for functions using ellipses!
Merge pull request #19 from Apollo117/improved_ellipses_with_tests

Improved ellipse struct to reflect lessons learned from the plane PR, with tests.
wrote more tests, noticed some design changes I may wish to write up
Merge pull request #20 from Apollo117/more_test_cleanup

wrote more tests, noticed some design changes I may wish to write up
updated README to be more current and to have installation instructions, showing progress.
Started adding new functions from new spice toolkit release, n65. This is a first pass at updating libspice.py and wrapper.py to write the wrapper functions. No tests for these new functions were added.
Merge pull request #22 from Apollo117/N65_new_functions_first

Started adding new functions from new spice toolkit release, n65. This is a first pass.
wrote more wrapper functions for new functions from new toolkit version n65, I think we are now back to writing tests.
Merge pull request #23 from Apollo117/more_new_funcs_n65

wrote more wrapper functions for new functions from new toolkit version n65
updated libspice.py to be less verbose with all of the 'ctypes.' calls, this may lead to the removal of libspice in favor of moving the c func signatures into wrapper.py so that only one file contains all of the wrapper componets (except for stypes).
Merge pull request #24 from Apollo117/experimental_refactor_libspicepy

updated libspice.py to be less verbose with all of the 'ctypes.' calls.
renamed supporttypes python file to be lowercase, fixed spicecell isset function to work, wrote tests.
