Subview optimizations, round 3
More changes to simplify the set of kernels and optimize expressions by avoiding submatrix extractions:
- Adapt
mean()
,var()
,median()
,min()
,max()
,sum()
, and other 2D-to-1D functions to allow subview arguments. - Remove specific submatrix variants of the functions above.
- Simplify and streamline
coot_rt_t
backend functions. - In a handful of places, use the subview arguments to avoid subview extractions.
Still not done yet, but these functions took a while to debug and refactor.
