When using AnalyzeTool() without a setup file, setting the Coordinates or States file name doesn't load either file.

From some workshop participants, they had code like the following (same is true if you use setStatesFileName() too):

analyzeTool = AnalyzeTool();
analyzeTool.setCoordinatesFileName('theirfilename.mot');
...

This throws an error at these lines, and it occurs because the bool _loadModelAndInput is false, skipping this line. The only way to switch that bool seems to be to construct an AnalyzeTool() with two arguments.
