Version 1.1

• Changed license from GPL3 to BSD
• Added single cage and double cage induction machine models (and example case)
• Added a voltage source converter (average) model
• Added option in machines file to use user-defined MVA base for machine parameters (impedances and inertia). Parameters are converted to 100MVA base during setup.
• Added version information
• Added STATE event for changine state variables during a simulation
• Speed-voltage term in current injections for synchronous machines is now an option (rather than always enforced)
