Add test case to check that simulators support their curated outputVariablePatterns

[jonrkarr]

1. Find a suitable example model encoded in XML
2. Use dependentVariableTargetPatterns XPATH patterns to generate a list of variable targets for the example model.
   • Find all objects that match the XPATH pattern
   • Generate unique XPATHs for each matching object
3. Create a data generator and data set for each matching object
4. Simulate example model
5. Check that data sets were produced for each matching object

(2) is likely difficult to automate because the specifications of dependentVariableTargetPaterns may not capture quite enough information to automatically generate XPATHs for specific objects.
