function specedit(x,f,action)
%SPECEDIT GUI for selecting spectral regions on a plot.
%  If input variable (x) is a vector SPECEDIT plots 
%  (x) [e.g. spectra] versus an optional input (f)
%  [e.g. wavelengths]. If (x) is a matrix of spectra
%  then SPECEDIT plots the mean of (x) where the rows 
%  of (x) correspond to different sample spectra and 
%  the columns of (x) correspond to different wavelengths.
%  Regions of (x) can be selected using push buttons.
%  The edited matrix input and column indices can be 
%  saved to the workspace interactively.
%
%I/O:  specedit(x,f)
