TComparable - Trait for adding comparison abilities to your object
This trait gives your object a wide range of comparison abilities through its overloading of the <=> operator.
This method should return -1 if $left is less than $right, 0 if $left
is equal to $right, and 1 if $left is greater than $right.
This fufills the requirement of the sub-trait TEquality.
