Update readme for create_bar, create_typical, and SpaceTypeAndConstrutionSetWizard measures

[DavidGoldwasser]

specifically the DOE versions but maybe others as well. There are new template choices and new building types. Here are links to some of the measures. Use code from new template measure to automatically get valid choices from extension gem so they are not hard coded in this measure. I also want to add a sentence or two explaining the new ComStock choices when using DOE templates. I'm going to hard code these in the measures for now but I'm also going to add to method in extension gem. Then when we update these measures again after 3.2 we can increase the min version and pull this from extension gem.

I think the readme and modeler description for create_typical_doe_building_from_model leaves something to be desired. In some instances I cannot get it to run and I do not know how to troubleshoot because there is no error information.

One example I can think of; the measure requires the user to select a climate zone for the field "!- Climate Zone Value 1". I think there is a lot more to preparing the model for using this measure, but it seems the modeler is left to grope in the dark.
