This provides a simple boolean attribute, which supports most of the basic math operations.
It is important to note that all those methods do in place modification of the value stored in the attribute.
Sets the value to 1.
1
Set the value to 0.
0
Toggle the value. If it's true, set to false, and vice versa.
Equivalent of 'not $value'.
$value
