Hi all,

I have a two-column matrix, containing trees in one column and a numeric value 
associated with each tree in the other column. I would like to go through the 
list to identify any duplicated topologies, and for each set of duplicates sum 
the corresponding numeric values and prune away the duplicate trees.

For example,

1.0   A
1.5   A
0.2  B
0.8.  C
1.0.  A
3.2.  B

Would become

3.5.  A
3.4. B
0.8.  C

Any help would be great!
