Figured out how to use java's variadic methods.
Changed interface to executingevent.  Java's reflection is supposed to
be really slow.  So instead of using it, compiler will have a dispatch
method that executes an endpoint method depending on the method name
passed in.
Finally finished adding LockedActiveEvent.  Now need to go on to
EventParent and Endpoint.
Added abstract class for event parent.
Added root event parent.  Must figure out some inheritance of call results, add basic endpoint operations, and then go for single-host transactions.
Changed inheritance for different message and endpoint call results to
mesh with java's type checker.
Minor type corrections.
Still slogging my way through endpoint.
Using strings for uuids and priorities for now.
Finished adding endpoint class.
Fixed a few type check errors caused by typos.
