# *can* validly have components from multiple plates: a user could
# chose to make a "plate pool" from more than one amplicon library prep
# plate. However, as of 10/09/2018, the wet lab apparently currently
# chooses not to do this, and instead chooses to make one pool per
# library prep plate. Given this self-imposed limitation, they expect
# to be able to have the (one-and-only) library plate name embedded in
# the name of the resulting normpool file. This
# *file naming convention* won't work--or at least, won't work as they
# expect it to--if there are multiple plates represented in the pool,
# so if that happens we generate an error below, at the point where the
# *file name* is generated. If they decide they want to allow
# themselves to make plate pools from multiple plates, all they need to
# do is decide on a more flexible naming convention, and
# we can change this naming code and remove this error condition.
