WS245 Test models for the New Construct class, mainly effecting existing tags in ?Transgene and ?Variation. Also contains Chris's ?Interaction Addition of DAase_I_footprinting to detection methods and my ?Clone End_sequence addition. I haven't added a dedicated Personal_communication to the #Evidence hash as it seems I was incorrect in my on the spot assesment of the use of Person_evidence in Hinxton so all Person_evidence can be take as personal communication.
