ConditionalExpression

class HPS::ConditionalExpression : public HPS::Object 

A ConditionalExpression is a string or collection of strings separated by logical operators. In practice, conditional expressions form a tree with the leaves being strings (the actual Conditions that must be satisfied) and the interior nodes being logical operators.
