SimMath Version 1.0.2

A small bug fix release with the following changes:

• Modified TransitionBuffer to have a 'clamp' on getTransition()
  that when 'true' will use the old behavior of returning the
  earliest/latest transition for out-of-range times. For 'false',
  it will return null for out-of-range times.
• Modified TransitionBuffer to remove the System.out.println() for
  out-of-range times.
• Modified the build.gradle to replace the JME version with a specific
  version instead of letting it float. I think alpha4 is generally
  the minimum accepted 3.1 version at this point.
