| Notes: | Parses the logical expression and splits it into individual | value expressions. Supports & for AND, | for OR and ! for | NOT. Supports parenthesis between individual terms: | (A|B)&(C|D) will turn into (A OR B) AND (C OR D) | Parenthesis will be threated as part of an individual | expression when a non " ", &, |, !, (, ) character has | started the individual expression. So | (A|B())&(C(test)|D) will turn into | (A OR B()) AND (C(test) OR D) where A, B(), C(test) AND D | will be passed as value expressions to the logical value | provider. | The Logical value provider is expected to return TRUE or | FALSE based on the given values |
