Q-constraint-operator SUM-TO


Slots on this q-constraint-operator:

Documentation:
Q+= is the q-operator for expressing an additive component of some

simulator variable.

Eg: (Q+= (Battery-1 current) (Term-11 current)) which asserts that

the current of Battery-1 is composed of a sum of which

the current thru Term-11 is a component.

A closed-world-assumption is needed to convert a bunch of such Q+= eqns

into a Q= eqn.
