Create a Fixed Boundary File from G EQDSK

A very simplified way to create a fixed boundary file from a G EQDSK is to run /link/efit/fixbndry. The interface is provided as run_fixbndry or from run_efit window under PostProcessor/FIXBNDRY.

Parameters for the fixed boundary file are either copied or converted from G EQDSK, or set to defaults. It calculates coefficents for P' and FF' if polynomial fitting is desired (ICURRT=2 for polynomial and 4 for spline fitting). Output file is named as r(shot).(time) which can be feed back to EFIT.

The plasma shape editor calls this code as well in generating a fixed boundary file. In that case, boundary and limiter data are passed in from the editor.
