A true expression is any expression that evaluates to anything other than a&lt;br /&gt;
false expression.  The following list are the recognized operators.  The&lt;br /&gt;
higher the operator is on the list, the higher the precidence.  The expression&lt;br /&gt;
is evaluated from left to right.  Parenthesises can be used to group.&lt;br /&gt;
