One issue I see immediately is that the "model options" for the TSA has a number of values and they will probably be changed at the same time / along with the model's other parameters and variables. However currently the UI sets these options in different, initial step, as shown by this screenshot for a watertap model:

This is, imho not ideal. We should have these sorts of model options more included in the main configuration page, even though they are not Pyomo vars.

@Daison2102 Do I have this roughly right about the FixedBedTSA0D model class?
@sspoon, @MichaelPesce thoughts on the design?

@dangunter the original purpose of those options were to allow for pre-build configurations, so it had made sense to be able to view them before running the build. however, they should also be available from the main workflow (after build step), where the model can be re-built with different model configurations

[dangunter]

@MichaelPesce ok, though I think it might be better to have them as normal parameters

Before merging, we should (* denotes items that are not strictly required):

• Add a dev dependency on idaes-flowsheet-processor @ git+https://github.com/watertap-org/idaes-flowsheet-processor@0.1.dev1
• (*) Add an entry point in setup.py pointing to the idaes.model_extra.temperature_swing_adsorption.fixed_bed_tsa0d_ui module under the idaes.flowsheets group
• (*) Enable testing using the idaes-flowsheets pytest plugin
