• Add drop downs for Study ID and Sample ID

• Separate the signal sheet, add to resources

• Update to xlsm and style

@cjmyers please review these templates:
https://github.com/SynBioDex/Excel-to-SBOL/blob/master/resources/templates/Resources.xlsm
and
https://github.com/SynBioDex/Excel-to-SBOL/blob/master/resources/templates/Study.xlsm

changed the name because it has data, not only metadata so may be confusing

Study dropdown is not working otherwise looks good.

Signal on resources is good.
