 * A driver for our different checkers:
 * 
 * todo:
 *  - use/def of global entities (functions, classes)
 *  - use/def of local variables
 *  - function/method call arity
 *  - dataflow based useless assignments
 *  - type checker (e.g. wrong type of argument, expr is not a bool,
 *    use of array instead of scalar, etc)
 *  - record checker (fields)
 *  - protocol checker, statistical analysis a la Engler
 *  - ...
