* Concrete implementaion of a single tuple
* In use, this class allows you to create a mathematical single which in PHP
* terms is an object containing exactly one item. This item can be of any
* type. Construction in through the 'new' keyword, e.g.
* $single = new Single('foo'); Once instantiated, access to the objects
* properties are via an array-type access, such as $value = $single[0];
* Trying to set values this way will result in an exception being thrown.
