List measurement set visibilities.

This task lists measurement set visibility data under a number of
input selection conditions.  The measurement set data columns that 
can be listed are: the raw data, float_data, corrected data, model data, 
and residual (corrected - model) data.

The output table format is dynamic.  Field, Spectral Window, and
Channel columns are not displayed if the column contents are uniform.
For example, if "spw = '1'" is specified, the spw column will not be
displayed.  When a column is not displayed, a message is sent to the
logger and terminal indicating that the column values are uniform and 
listing the uniform value.

Table column descriptions:

COLUMN NAME       DESCRIPTION
-----------       -----------
Date/Time         Time stamp of data sample (YYMMDD/HH:MM:SS UT)
Intrf             Interferometer baseline (antenna names)
UVDist            uv-distance (units of wavelength)
Fld               Field ID (if more than 1)
SpW               Spectral Window ID (if more than 1)
Chn               Channel number (if more than 1)
(Correlated       Correlated polarizations (eg: RR, LL, XY)
  polarization)     Sub-columns are: Amp, Phs, Wt, F
Amp               Visibility amplitude
Phs               Visibility phase (deg)
Wt                Weight of visibility measurement
F                 Flag: 'F' = flagged datum; ' ' = unflagged
UVW               UVW coordinates (meters)


Input Parameters:
vis         Name of input visibility file
    default: none; example: vis='ngc5921.ms'

options     List options: default = 'ap'
    Not yet implemented for suboptions

datacolumn  Visibility file data column:
    default = 'data':  options are
    data, float_data, corrected, model, residual (corrected-model)

field       Select data based on field id(s) or name(s)
    default: ''==>all; example: field='1'
    field='0~2' field ids inclusive from 0 to 2
    field='3C*' all field names starting with 3C

spw         Select spectral window, channel to list
    default: '0:0' --> spw=0, chan=0
    spw='2:34' spectral window 2, channel 34

selectdata  Toggle the following 7 selection parameters.
    default: False; example: selectdata=True
    If false, the following parameters are reset
    to default values.

      antenna     Select calibration data based on antenna
  default: ''-->all; examples: 
  antenna = '5,6'; antenna index 5 and 6 solutions
  antenna = '05,06'; antenna names '05' and '06 solutions
 
      timerange   Select time range to list
  default: ''-->all; examples:
  timerange='10:37:50.1'; list data for this sampling interval
  timerange='<10:37:25'; list data before 10:37:25
      
      correlation Select polarization correlations to list
  default: ''-->all; examples: 
  correlation='RR LL'; list RR and LL correlations
  correlation='XX XY'; list XX and XY correlations
      
      scan        Select scans to list
  default: ''-->all; examples:
  scan='2'; list scan 2
  scan='>2'; list scan numbers greater than 2
      
      feed        (not yet implemented)
      
      array       (not yet implemented)

      observation Select by observation ID(s).
  default: ''-->all;
  example: observation='0' (select obsID 0)
      
      uvrange     Select baseline lengths to list.
  default: ''--> all; examples:
  uvrange='<5kl'; less than 5 kilo-wavelengths
  Caution: Input units default to meters.
  Listed units are always wavelengths.

average     (not yet implemented)

showflags   (not yet implemented)

pagerows    rows per page of listing
    default: 50; 0 --> do not paginate

listfile    write output to disk; will not overwrite
    default: '' --> write to screen
    listfile = 'solutions.txt'

async       Run asynchronously
    default = False; do not run asychronously
