This means that the component will still show up in the graph or representation of the circuit, and can still have its value assigned interactively, or from within a loop.When the value of a component is "NL" or "NC", add the component to the circuit but have the solver exclude such components from the calculations.

This probably won't work for large circuits, but for small one it surely will.
Related: for displaying the results, adapt the LaTeX equation code in `display.py`.As with #7, it should be possible to implement a symbolic solver using e.g. Sympy. This probably won't work for large circuits, but for small one it surely will.

It should be possible to use Cython code to interface with the library. Now that the solver has been split off from the `Circuit` object (e774a0d0) this should be quite straightforward to do. With the same library it should be possible to produce identical results to LISO.
Note that this will probably need a Makefile to run during `setup.py`.LISO uses the SPARSE library for circuit simulation. It should be possible to use Cython code to interface with the library.

Could take this a step further and allow multiple parameters to be varied at once.
Could also allow the user to specify a generator for the x-axis, to allow for adaptive simulations, i.e. ones where the next frequency is calculated based on the gradient between the last two, to allow more points to be simulated near where interesting features occur. Could maybe provide such adaptive generators in the toolbox.Allow the user to set a particular frequency and then vary e.g. resistor values and plot the results, instead of always having to vary frequency.
