number_sats_in_dataset

 number_sats_in_dataset Number of satellites used to characterise dataset

 Some datasets, such as collocations_mhs_mhs, need 2 satellites to
 characterise it; most need only one. This function gives the answer.

 FORMAT

   n = number_sats_in_dataset(d)

 IN

   d   string      dataset name

 OUT

   n   number      number of satellites to characterise
