QuadTune: Introduce new utility function to create scatterplots and plot first 2 SVD components.

For #910.

I am copying the round-off level changes made to grid weights
and grid interpolation functions from the generalized_grid branch
over to the master branch. This is being done ahead of merging
code from the master over to the generalized_grid branch.

This code is necessary to get results in the generalized grid
branch bit-for-bit between ascending and descending grid
directions when optimization is set to -O0.

This change produces changes at the numerical round-off level
in the affected calculations, making this commit BIT_CHANGING.

Plots show lines overlap for almost all cases besides the most
sensitive cases (ARM 97, TWP ICE, etc. -- looking at those
shows you how much of a difference a simple numerical round-off
can make).
