Dinucleotide frequencies

This routine simply counts dinucleotide frequencies for the selected region of the sequence. It also calculates an expected distribution based on the base composition. The output looks like:

        A                C                G                T
     Obs    Expected  Obs    Expected  Obs    Expected  Obs    Expected
 A     7.91    5.84     5.64    5.93     5.05    6.49     5.57    5.91
 C     5.91    5.93     5.14    6.02     7.38    6.59     6.10    5.99
 G     6.11    6.49     7.56    6.59     6.30    7.22     6.90    6.56
 T     4.24    5.91     6.18    5.99     8.14    6.56     5.86    5.97
