axiom holds for all times

## Elucidation
This is used when the statement/axiom is assumed to hold true 'eternally'
## How to interpret (informal)
First the "atemporal" FOL is derived from the OWL using the standard
interpretation. This axiom is temporalized by embedding the axiom
within a for-all-times quantified sentence. The t argument is added to
all instantiation predicates and predicates that use this relation.
## Example
Class: nucleus
SubClassOf: part_of some cell
forall t :
forall n :
instance_of(n,Nucleus,t)
implies
exists c :
instance_of(c,Cell,t)
part_of(n,c,t)
## Notes
This interpretation is *not* the same as an at-all-times relation

## Elucidation
This is used when the first-order logic form of the relation is
binary, and takes no temporal argument.
## Example:
Class: limb
SubClassOf: develops_from some lateral-plate-mesoderm
forall t, t2:
forall x :
instance_of(x,Limb,t)
implies
exists y :
instance_of(y,LPM,t2)
develops_from(x,y)
