Add a check in IntracellularRecordings.add_recording to ensure we don't add incompatible stimulus and response series (i.e., make sure we don't mix CurrentClamp with VoltageClamp data)
Add test to make sure the error is raised
Update example notebooks to remove use of incompatible types in the example
Fix #22
