Fix #240. The problem was that the TSMeta object in a TreeBuilder was overwritten by a subsequent call to processTimeseriesMeta() before the branches could finish processing. Thus, when it came time to store the results, the branch replaced with data from the last TSMeta instead of the one we wanted to process. Now we create new TreeBuilder objects for each TSMeta using one set of Trees and it is working correctly.
