Detailed Description

Interval variables are often used in scheduling. The main characteristics
of an IntervalVar are the start position, duration, and end
date. All these characteristics can be queried and set, and demons can
be posted on their modifications.

An important aspect is optionality: an IntervalVar can be performed or not.
If unperformed, then it simply does not exist, and its characteristics
cannot be accessed any more. An interval var is automatically marked
as unperformed when it is not consistent anymore (start greater
than end, duration < 0...)
