How to save MeshGems-SurfOpt Parameters
=======================================

MeshGems-SurfOpt hypothesis is not a meshing hypothesis for Salome, but an hypothesis for MeshGems-SurfOpt.
The current set of parameters is automatically written in the Salome study object browser when you run computation.

These parameters could also be stored in a special file.
Default file is $HOME/.MGSurfOpt.dat.
This ASCII file is appended, and never cleaned.

In frame "Plug-in Generic Options":

- To save the current setting in this file, click on "Save" pushbutton.
- To load the last set of parameters saved, click on "Load" pushbutton.

At the bottom of the dialog window:
  
- To save a current setting in the study object browser, click on "Save" pushbutton.
- To load a current setting from the study object browser, click on "Load" pushbutton.
- To load the default setting, click on "Default" pushbutton. .
