class Interval
Tests if a given number belongs to a given math interval.
An interval can represent a finite set of numbers:
{1,2,3,4}
An interval can represent numbers between two numbers:
[1, +Inf] ]-1,2[
The left delimiter can be [ (inclusive) or ] (exclusive). The right delimiter can be [ (exclusive) or ] (inclusive). Beside numbers, you can use -Inf and +Inf for the infinite.
