tweaks to test argwhere, far from being succesffull...)
making progress
reached last ind -general case- and checks ok for test point
still some loops - working but CPU 126 sec ! loop on interpolation is a killer
removing npy.where in interp solved the efficiency issue - down to 3.5 sec /month
further clean up and plot test - ready for merge back in master
before merge
merge with master
Merge branch 'no-i,j-loop'
