Code-breaking updates in 4.0.0 about basiclinearalgebra HOT 3 CLOSED

Hey @bobthefairycat , thanks for the information! I guess in my update to 4.0.0 I missed the unary operator-, I'll push a change for that in a moment.

As for the implicit casting from float to double that you pointed out, the cause is as you discovered on #64. It wasn't explicitly intended to disable these implicit casts in 4.0.0 but at the same time they're kind of notorious for being bug prone so I think it might be for the best that it's flagged as an error.

FWIW you can also use the Cast<T> to convert a Matrix it into a different datatype for example:

double y = 1.0;
Matrix<2,1, double> tmp = z_hat.Cast<double>() - y;

Ok, I reinstated the operator- with version 4.1. Let me know if you have any more trouble!

I appreciate the effort to fix the bug! To be "safe", I packaged out the project with instructions to use 3.7.0 (use case is educational in a very limited setting, so unlikely that the oversights allowed will be problematic).

Thanks again!
