# Handles the generation of two 96-well child plates from up to four 96-well source plates.
# In the client, the user will be able to scan 1-4 96-wells plate barcodes to
# create a pair of 96-well plates.
# Transfers are the first 3 columns from each of the four sources, into sets of 3 columns
# on the destination (source 1 to columns 1-3, source 2 to columns 4-6, source 3 to columns 7-9,
# and source 4 to columns 10-12).
#
# Eg.
#
# Plate 1        Plate 2         Dest. Plate
