Development
simple null check
Markup support so developers can register different markup engines and the UI can reflect it. Also, updated lots of JSON incompatibilities with Railo and Adobe CF CONTENTBOX-101 #close
removed secondary cache to avoid setup errors. Users will need to optimize this manually.
