For example channel_width has a getter and setter. Does this need to be set in terms of N0 (number cells) or N0_meters (meters). Does this automatically reinitialize the necessary DeltaModel internals to actually make the change take effect? Need documentation and tests on these.

Relates to BMI_pyDeltaRCM.
