Testing I've completed

@nickbianco This should fix the lingering matlab test failures for developers who happen to have matlab locally installed. Also to make our published codebase/tests consistent with our own API. Not urgent since broken for years..

Looks good! I just had one quick comment, but it's not blocking.

Bindings/Java/Matlab/tests/testOsimC3D.m line 111 at r1 (raw file):

            assert(abs(d.get(0)-d_m.get(0))<.001,'Force Data has been incorrectly altered');
            assert(abs(d.get(1)-d_m.get(1))<.001,'Force Data has been incorrectly altered');
            assert(abs(d.get(2)-d_m.get(2))<.001,'Force Data has been incorrectly altered');

I assume these tests were failing to some relatively high precision?

Thanks @nickbianco The old test was using plain equality of doubles after performing transformation/matrixt multiplication!

Thanks @nickbianco 👍
