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.
- compare ($left, $right)
- 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 $right.
- equalTo ($left, $right)
- This fufills the requirement of the sub-trait
