[CLEAN\]UV_CHOP InputUV KEY OutputUV

Chop into pieces the input UV table specified by InputUV and place the pieces in separate files of names OuputUV-1 ... OutputUV-N. The pieces are determined by the keyword KEY:

   DATES   Split the data by observing dates (time does not count, so
           there will be separate files for continuous observations
           around midnight
   FIELDS  Split by pointing/phase directions

UV_CHOP InputUV FIELDS OutputUV is thus similar to

   UV_MOSAIC InputUv SPLIT OutputUV

except that is produces degenerate 1-field mosaics instead of simple independent single-fields.
