Easy projects for new developers
- Jun 2016: I might as well gripe about the inconsistent capitalization of mxOptions - “Number of Threads” but “Default optimizer” etc. It’s easy enough to remember what an option is called, much less so to figure out the capitalization.

I see no scenario where different selections based on different capitalization would occur in mxOption().
