If user supplied dendrogram has different labels than supplied matrix, system should throw an error.

[jmelott]

Currently if a user supplies a dendrogram with simple labels of just the primary label, while the matrix has a complex label with fields separated by bars, the map ends up with the simple labels that were in the dendrogram rather than the longer complex ones. This causes all of the link outs that use the additional columns to fail as all the entries are undefined.
