public class Condition
This class describes a condition in a general meaning. A condition can either be
1) Atomic (a=10, B='aa')
2) Composite ( NOT Condition1 AND Condition2 OR Condition3 )
If the nr of atomic conditions is 0, the condition is atomic, otherwise it's Composit.
Precedence doesn't exist. Conditions are evaluated in the order in which they are found.
A condition can be negated or not.
