Piecewise Chamber and Valve

Added Piecewise Chamber and Valve

Current situation

I developed I model based on the equations outline in Regazzoni's heart model which required the implementation of a new heart block as well as new values.1

@rjrios915, please review all files/folders in this PR and check if you actually intend on modifying them (see comments for #202).

I'll take this and #202 over and try to get this fixed up asap as there is renewed interest in the lab for this feature

[ncdorn]

alright I think i've cleaned this up. @mrp089 there is one discrepancy - on my local machine the tests for cases with a valve are not passing as the result solution contains the new valve_status variable. however for some reason the tests pass fine on teh Github CI pipeline. I have updated the reference solutions to include the valve_status variable which is why the tests are not passing. any thoughts on why this is happening? is Github CI not using the most up-to-date build?

[mrp089]

Nice! The failing test cases show up as modified. You have to check them out from master and commit them to reset.

alright this should be all cleaned up and ready to go! @mrp089 let me know if I missed anything here
