trufflesteeeveandahmed 114f4b6989 Add Type() to detector interface (#1088)
* Add Type() to detector interface

The goal here is to allow the detector type information to be used
without the need for reflection. This could possibly allow us to more
easily inject information into detectors or filter them out if
necessary.
