Arne can test.

The same page handles both single and multi model selection, we want to use radio buttons in the single model case to avoid doing error checking on submit to ensure only one model was selected.
We use check boxes for the multi model case.

when creating the html control, the name of the control is "model_" for single model and "model_" + model id number for multimodel. This simplifies the next web page because it can handle both cases in the same way.

Tried other ways of handling this, this seemed the most simple to me, but there is likely a better way because this is still somewhat messy.
