NAME

TComparable - Trait for adding comparison abilities to your object

DESCRIPTION

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 TEquality.
