`parameters.py` defines a set of activity types to record basic
medical parameters. They have in common that they are not measurements
like the observations.
They can represent a patient state, flag or any simple medical
information that is not measured, but set by the medical staff.
They are represented by activity types mainly for audit purposes as
their static nature would allow them to be fields instead. The last
completed one would represent the current status regarding that specific
parameter.
