launch FDTD sim from INTERCONNECT; register Sparam into CML in INTERCONNECT

For the Directional Coupler, which is already in the PDK. The DC has many parameters (g, w, r, length, wavelength range) hence providing a full parameter sweep is not reasable. The user may ask for a component that hasn't been simulated (e.g., w = 300 nm, g = 250 nm, L = 1.5 µm, r = 9.9 µm, lambda = 1310 nm). Need a method to get this filled in:

• in KLayout, user launches a simulation; INTERCONNECT issues a warning that the model doesn't exist and the simulation isn't accurate.
• INTERCONNECT launches FDTD; result is S-parameters
  • user registers the Sparam model into the CML (eventually automated):
  • KLayout launches INTERCONNECT, to find out the path of the EBeam CML. ?get("local path");
  • KLayout copies the Sparam file into the CML, and edits the XML file to add the new component
• INTERCONNECT now has the correct model.

For new components / user generated components, if the user only wants to simulate the SParams:

• use the above item, of launching FDTD to get Sparam.
• if someone wants to add this to the PDK, they would manually edit the CML directly.
