Matlab bindings now only building once rather than every call to make, via the use of some proxies. Matlab build currently only happens in one thread, so it can be pretty slow

input/output assignment in templates is working for non-trivial cases. Updated parse_tree to handle '/IO' and '/S' modifiers

Started handling trivial case of return references. Removed most modules from build tree while testing (cmake/OpenCVModule)

cmake now attempts to generate and compile a simple mex file at configure time and reports the working status of the generator and compiler, rather than just naively saying Matlab exists

Stripped more unnecessary files out of jinja. Now down to 21 files at 352KB. Stripped files are in jinja-unused for the moment

Added basic ability to find Matlab installations. Added test cpp file under modules/matlab/test to test mex compiler within cmake

Add a new variant of detectMultiScale with output arguments 'objects' and 'numDetections'; factor most of detectMultiScale's code into 2 protected methods

Python 3 requires METH_VARARGS | METH_KEYWORDS, not just METH_KEYWORDS.
