Write 2D LUT

[bigfooted]

Proposed Changes

Give a brief overview of your contribution here in a few sentences.

• write 2D LUT when min,max mixture fraction levels (or equivalence ratio levels) are the same and number of levels is 1
• use restart file, cantera solution from previous run (inside the loop)
• interpolate between last burner stabilized flame and final equilibrium point to get smooth interpolated flame solutions in the low enthalpy region
• modify visualization
• make mesh width a config option
• make loglevel a config option
• make Tgen.SetEquivalenceRatioLimits(phi_min=0.80,phi_max=0.80) a config option
• fix equilibrium point, only use final low enthalpy point
