//------------------------------------------------
// Auto add negative keywords to dynamic campaign
// Created by: Remko van der Zwaag & PDDS

// More info: http://goo.gl/64PrMT
// 26-05-2015: Added Hybrid functionality
// 17-09-2015: Switched to negative keyword lists,
//             among various other changes
// 16-03-2016: Inclusive version (eg. specify
