Updated Timeline.java and JavaSystemCaller.java to use array version of
Runtime.exec() method as the most recent version of Java (1.7.0_21)
changed the behavior of the single-string version of Runtime.exec()
causing a problem with Timeline. Also updated code to so that the
mactime output is no longer redirected to a file via the '>' redirect
operator. The ouput is now being captured from JavaSystemCaller.execute()
and written to a file directly.
