<Purpose>
Uploads a file to a set of vessels. A batch wrapper around the Experiment

<Arguments>
vesselhandle_list
A list of vesselhandles of vessels to which the file is to be uploaded.
filename
The filename of the file to be uploaded.
<Exceptions>
None
<Side Effects>
None
<Returns>
A list of vessels to which the upload succeeded.
