Version 2.0.0 Release Candidate 1

The following edits and improvements to INGRID are presented in this version 2.0.0 release candidate.

• Class Bicubic in interpol.py has been replaced with scipy.interpolate.RectBivariateSpline for a significant performance boost to the core bicubic interpolation scheme.
• Module OMFITgeqdsk has been reintroduced for the handling of reading EFIT data.
• Visualization improvements remove jagged contour lines when inspecting EFIT data. Legend placement has been adjusted.
• API edits to ingrid.py
  • PlotGrid added to API. PlotSubgrid is still available for use, but will be depreciated.
