changed argument name of multmatrix() to m from n
-- expanded euclidify() to accept list arguments.
-- Added euc_to_arr(), the inverse of euclidify()
-- added simpler transform_to_point() which accepts OpenSCAD or PyEuclid objects
-- Refined extrude_along_path().  Works well, but fails on paths of the form [[0,0,0], [0,0,10]]
-- extrude_along_path() endcaps are incorrect with convex shapes.
Small changes to utils.py in euclidify() & euc_to_arr().
Added incomplete unit tests for solidpython & utils
updated TODO
Added __init__.py to solid.test so it gets installed.
-- Cosmetic changes, TODO note
