Some functions should probably be const

[giannitedesco]

Lots of methods could be const, particularly constructors, and conversions from column/row oriented and back.

That way you can have static/const vectors/matrices etc..

There was a discussion on this in #12 , you may want to search for The only function I've been able to make const was new() for vectors in that thread.

Then again, that may be outdated. It's been a few years...

Yeah pretty sure it is, I can't see why broadcast, conversions, maps, casts, the like can't all be const
