put something together, see [1].

- a "probe" function (requires a patched expression parser [2]). this
  allows you to access probes from parameter expressions.
- an "expression evaluator". inspired by the (dysfunctional) qucsator
  "eqn" device. it takes as many parameters as you like. these are
  evaluated (in order) during simulation. the values are accessible as
  probes.
- an integrator. takes one parameter expression as argument. provides
  the integral as a probe.

all of this does not use nets and nodes. you cant model components with
it, but that's not the intent! .. just see the included example (.gc
files).
