Revert "Moved all Input Capture code for the RC node into C code."

This code was incomplete and should never have been completed in the first place. I'm not deferring any changes to the RC node as they're unnecessary at this stage.

This reverts commit 9f3719c46f3f123d4cf259457b6fa8d1dfae40b7.
RC Node: Updated the Simulink model to correctly include the DEE library.
