<Purpose>
Runs a program on a set of vessels. A batch wrapper around the Experiment
Library function run_parallelized, with logging support.
<Arguments>
vesselhandle_list
A list of vesselhandles of vessels to which a file is to be uploaded.
filename
The filename of the program to run.
*args
Optional additional arguments required by the program to be run on
vessels.
<Exceptions>
None
<Side Effects>
None
<Returns>
A tuple of:

which the program succeeded and failed to run, respectively.
