[cctbxbb] scitbx without numpy - still supported?

Hi All, I've been tweaking the code to allow versions of boost higher than 1.63, which has involved poking at the scitbx-numpy bridge code. There seems to be some level of branching in the code for supporting building without numpy - but on the other hand numpy seems to be used exclusively for all flex.type.__init__ functions that I can find? Is building without numpy still supported? Thanks, Nick
