turn off 3d shapefile reading by default

CHLNDDEV / OceanMesh2D

A two-dimensional triangular mesh generator with pre- and post-processing utilities written in pure MATLAB (no toolboxes required) designed specifically to build models that solve shallow-water equations or wave equations in a coastal environment (ADCIRC, FVCOM, WaveWatch3, SWAN, SCHISM, Telemac, etc.).

turn off 3d shapefile reading by default #121

Closed krober10nd closed 4 years ago

krober10nd commented 4 years ago

If a shapefile has a height (for whatever reason), previously it would trigger a very expensive set of operations on it that were invented for GLOCOFS and not for typical mesh generation.
This PR deactivates this behavior when a 3D shapefile is detected and lets the user give an option to geodata to turn it on shapefile_3d (0,1 boolean)
