Description

I use Commons Math heavily, and have adopted its Pair class for the cases where I need, well, a pair of things.

The attached patch adds three small improvements to the Pair class:

• toString() method
• factory method ".create()" to avoid duplicating generic types on instance creation
• a Comparator

Tests are included. I won't feel offended if this is rejected or modified but just wanted to supply the suggestion.
