Adjust for longer structure names in MDX files
Current "perception" module requires data from Systems library. It says that LeafSystem and System are not found.
System's MDX file contains the following information:
{"drake::systems::LeafSystem<double>": "apb11_systems_module", "drake::systems::System<double>": "apb11_systems_module", "SystemBase": "apb11_systems_module", "SystemMessageInterface": "apb11_systems_module"}
Adjust MDX information to have the shortest name? Adjust the lookup to use the longest structure name?
