Scalameter for java code

Please note that I've worked on version forked from http://axel22.github.com/scalameter/.
Also, I have a NullPointerException at the end of regression tests, even with scala code coming from HTMLReporter.scala at line 167. I have not been able to determine if it comes from my code, or my computer...
These should end up being static methods in the `Aggregator` companion object, so they should be callable from Java. Did you try to call `org.scalameter.Aggregator.min`?

We should have this:

    package org.scalameter.japi
    object Aggregator {
      def get = org.scalameter.Aggregator
    }

Java clients would then call:

    Aggregator.get.min
