11	* Class FilterVarValidateBool
12	* see tests. FilterVar will return true for case-insensitive strings of true, yes, on and the character 1.
13	* Returns false for case-insensitive strings of false, no, off and 0. The FILTER_NULL_ON_FAILURE sets the behavior
14	* so that it returns null if the string argument is some other string. So we need to override the validate method
15	* inherited from the parent class because this flavor of filter_var behaves like a parser, not like a validator. In
16	* other words, we want to return true if the input is true or false, and return false if it is some other non-boolean
17	* kind of string such as 'foo'
