file to file Bank Of Tuners application using ICE card accelerator

<in>     Input file
<out>    Output file
<device> ICE card alias
<nchn>   Number of channels
<dec>    Tuner decimation
<freq>   Tuner frequency (channel 0)
<dfreq>  Tuner channel spacing

This command uses an ICEPIC to channelize a Midas file on disk.  The output is a single
type 2000 file with blocks of data frames. Each block contains one frame for each channel 
in succession from channel 1 to <nchn>.  The CHANNELS keyword indicates the number of 
frames/channels in each block.

Individual channels can be extracted using the thin command followed by HEADERMOD
  nM> thin in=blockdatafile out=channeldata start=<channel> end=-1 inc=<nchn>
  nM> headermod channeldata type=1000

Switches:
  /AFLAGS=s Special flags to apply to ICE card
  /RSIZE=n  Ram buffer size in seconds
  /OFORM=n  Output format (SI,CI)
  /PBRATE=n Playback rate in Hertz (must be less disk access speed, default=25MHz)
  /GAIN=n   Tuner gain in db
  /PLOT     Show spectral plot of results
