Description

Create a new version of GetEI that should

  1. If not given an ei_guess make a sensible guess
    1. Either by reading set value from the run object
    2. or taking the ighest value in the spectra (once converted to distribution)
  2. Attempt to model ei by fitting a suitable curve function (best ikeda carpenter - need to talk to anders about parameters, possible a simpler function)
  3. Fall back to using the moments analysis if the curve fitting fails.

This may duplicate some of #1681
