NAME:
  iota2lc
 PURPOSE:   (one line only)
  Read an IOTA cvs lightcurve file and convert to a simple text table
 DESCRIPTION:
 CATEGORY:
  Photometry
 CALLING SEQUENCE:
  iota2lc,fnin,fnout
 INPUTS:
  fnin - Name of the input file
  fnout - Name of the output file, default is fnin with the trailing .csv
             changed to .lc
 OPTIONAL INPUT PARAMETERS:
 KEYWORD INPUT PARAMETERS:
  TCORR - camera and integration offset to add to timing [seconds]
             t_final = t_file + tcorr
  DCOL  - column(field) for the data, default=3 (the code is not general inside)
  WIDE - flag, if set forces condition of 10 or more columns
  BINFAC - measurement binning factor to compensative for video frame
             integration, Default = 1 (no binning)
  OFFSET - Trim this many points from the start of a lightcurve so that the
             the binned points match the integration boundarries.  The
             default is zero.  This value is constrained internally to be
             between 0 and binfac-1.
  N_HEADER - number of lines to skip before the column header
