Changeset 1217 for trunk/examples

adding ability to specify runfiles to be either loaded or included with the
results of the current simulation. loading a runfile will simply call the tool object's load function within analyzer and the runfile will be loaded as a previous simulation result. including a runfile involves copying the results (everything under output) from the runfile into the current run.xml file and all of the results are shown as one single simulation.

This behavior is demonstrated in the zoo's loadrun example.
