Finding the relationship between two ranges

[GoogleCodeExporter]

Could you please add methods to check if 2 ranges intersect or are continuous? 
The current methods provide no convenient way to perform these checks.

intersects would look like this:
public boolean intersects(Range<C> other) {
  Cut<C> intersectionLower = Ordering.natural().max(lowerBound, other.lowerBound);
  Cut<C> intersectionUpper = Ordering.natural().min(upperBound, other.upperBound);
  return intersectionLower.compareTo(intersectionUpper) <= 0;
}

isContinuous would look like this:
public boolean isContinuous(Range<C> other) {
  return upperBound.equals(other.lowerBound);
}

It turns out there are at least, like, 11 different relationships two ranges 
can have, and we're thinking about how to properly address the important ones.  
I will try to paste more detail when we get closer to actually working on it.

Does 
http://docs.guava-libraries.googlecode.com/git-history/v10.0/javadoc/com/google/
common/collect/Range.html#isConnected(com.google.common.collect.Range) do what 
you need?

Yes, that does what we need. Thanks!

Do we want to keep this issue open in case people need other range relationship 
tests?
