These utilities are provided
as additional routines to help with xmap8 data.

hypohull = takes in hypocenters, points or XYZ triplets
           and creates a 3D convex hull output in a wireframe structure
           suitable for reading into xmap8.
           Given > 200-300 events it is fairly slow.

SDR_to_UW = strike/dip/rake  triplets converted to UW format focal mechs



fpf2uw  = fpfit output converted back to UW format

gmt2lees.p = perl program to convert gmt maps to xmap8 format (smart)


Up2LowerFoc  = converts and Upper hemisphere to lower hemisphere focal mechanism

parrow  = makes arrows out of P and T axes
