Fit: still something wrong with chi^2 error computation -- fix it
  * chi^2 error is inexplicably low on some horribly inaccurate curves
  * large bin radius results in discontinuities in bright areas?
  * 2-component fits can be inaccurate (see Log scale for confirmation)

2D: pixel probe in lifetime mode
  * show details on curve fit result for that pixel
  * report information beneath 3D plot where view toggles used to be

3D: fix bug in FWHMs when pixel probing
3D: fix bug in yellow lines when toggling individual channels

2D: implement spectral projection view
2D: implement emission spectraview

Improve results in the circled region first

The larger the chi2, the dimmer the pixel could be? I.e., ability to plot
different parameters in 2D lifetime window to three different color components

Use forms for GUI

Numbers for RENDERER:
  - Phase, percent complete
  - Iteration #
  - Worst RCSE
  - Total RCSE

Numbers for active CURVE FITTER:
  - a1 raw, a1 %
  - t1 raw, t1 ps
  - a2 raw, a2 %
  - t2 raw, t2 ps
  - c
  - chi^2 raw, chi^2 reduced

Improve export button: also export curve statistics for current curve,
including formulas -- makes it easy to duplicate plot in Excel
