Disable parameters or sources based on other checked parameters or sources.

Use case #1:
I "check" Lake Erie Commission as a data source. So we should "disable" parameters that are not part of that data. All other "sources" will remain enabled.

Use case #2:
I "check" the parameter for "Chlorophyll-a". The data sources that have Chlorophyll-a will be selected, and those sources that don't will be disabled. All the other parameters will remain enabled.

So it seems like for this to work, checking a box in Parameters will disable Data Sources, and checking a box in Data Sources would disable Parameters; but it doesn't seem like checking a box in Data Sources should disable other Data Sources, nor should checking a box in Parameters disable other parameters.

Use case #3:
If I "check" an area, like Lake Michigan, Data Sources and Parameters not in that area will both be disabled.

So it seems like Areas should be able to disable both Data Sources and Parameters.
