Assignments represent a change that happens to the value of a StateVariable during a transition between regimes.
For example, in an integrate-and-fire neuron, we may want to reset the voltage back to zero, after it has reached a certain threshold. In this case, we would have an OnCondition object, that is triggered when v>vthres. Attached to this OnCondition transition, we would attach an StateAssignment which sets v=vreset.
The left-hand-side symbol must be a state-variable of the component.

link to something about visitation.
Returns a python callable which evaluates the expression in namespace and returns the result
returns True if at least 1 function on the RHS is not in the math namespace
Replace atoms on the RHS with values in the name_map
Returns a list of the atoms in the LHS and RHS of this expression
Returns an iterator over all the variable names and mathematical functions on the RHS function. This does not include defined mathematical symbols such as pi and e, but does include functions such as sin and log
yield names of functions in the RHS which are not in the math namespace
