class tom.ConditionClass

Instances of the ConditionClass define the hierarchy of conditions as carried by Condition instances. Conditions classes could be real tom classes, but the features provided by said mechanism are too baroque for this purpose---only the inheritance is needed.

The tom condition class hierarchy does not employ multiple inheritance.

TOM conditions are evidently modelled after CL.
