NAME: 
  lcfunf
 PURPOSE: 
  Compute a lightcurve function independent variables.
 DESCRIPTION:
  This is to be used in cases where you already know the fundamental period.
  The input independent variable is assumed to be reduced to phase of a
  fundamental period already.  The integer part of the number is not used
  by the function.
 CATEGORY:
  Mathematical
 CALLING SEQUENCE:
  ans = lcfunf(x,m)
 INPUTS:
  x - independent variable (longitude, between 0 and 360)
  m - order of fit (see lcfun.pro)
 OPTIONAL INPUT PARAMETERS:
  PHANG - phase angle of each observation, will be saved to common, if
             not provided will use the last values saved to common block.
             Angle is in degrees.
 KEYWORD INPUT PARAMETERS:
 OUTPUTS:
  return value - 2-d array with all the independent variables computed.
                    This is normally used to setup a svdfit or similar
                    operation.
 KEYWORD OUTPUT PARAMETERS:
 COMMON BLOCKS:
   lc_com - one variable, phang, that is used to save the phase angle from
               one call to the next in case of calling the lcfun or lcfunf
               from a canned routine that cannot be taught to pass the
               extra independent variable.
