Specimens/Measurements download return needs to be modified

[markuhen]

Currently, one can either download data for specimens OR measurements, but there needs to be a mashup of the two returns to make the measurement data useful. Basically, all of the columns in the Specimens return need to be added to the Measurements return to make it useful. The only way to link the two downloads currently is via the specimen_no parameter, which could be done after downloading each separately, either by hand or by script, but I'm sure that most users would like us to do that for them, so we should.

Perhaps we should allow users to do either one of the two returns we currently offer, as well as a mashup of the two. See the attached file for an example of a mashed up return.
