* Concrete implementaion of a pair tuple
* In use, this class allows you to create a mathematical pair which in PHP
* terms is an object containing exactly two items. These items can be of any
* type. Construction in through the 'new' keyword, e.g. $pair = new Pair(1, 2);
* Once instantiated, access to the objects properties are via an array-type
* access, such as $value = $pair[1]; Trying to set values this way will result
* in an exception being thrown.
