class ConversionError (reagent, molarity, total_vol, ratio, empty_reagents)

This is an error used by the controller raised during the conversion from molarity to volume.

This exception really encapsulates two errors, a volume transfer that is too small, or a volume transfer that is trying to transfer from a solution you've run out of. In the former case, empty_reagents will be empty. In the later case, empty reagents will contain a list of reagents that could be refilled in order to make this work.
params:
str: reagent: the reagent that is being used
float molarity: the desired molarity
float total_vol: the total volume in the container you're filling
float ratio: the ratio of total volume. See convert for details
list empty_reagents: a list of chemical names that could be used, but do not have sufficient volume left for the transfer.

class EmptyReagent (message, chem_name)

This is used for when you run out of a reagent on a container and try to aspirate from it.
Specifically it can be used for triggering a make.

params:
str message: the message associated with the error
