Deferred feedback with CBM and explicit validation question behaviour

This Moodle question behaviour was created by Tim Hunt of the Open University.

It is like the standard deferred feedback with CBM behaviour, but with the addition of a 'Check' button that the student can click to get Moodle to check the syntax of their response. This question behaviour was created for use with STACK https://github.com/maths/moodle-qtype_stack/

To install, either download the zip file, unzip it, and place it in the directory moodle\question\behaviour\dfcbmexplicitvaildate. (You will need to rename the directory moodle-qbehaviour_dfcbmexplicitvaildate -> dfcbmexplicitvaildate.) Alternatively, get the code using git by running the following command in the top level folder of your Moodle install: git clone git://github.com/maths/moodle-qbehaviour_dfcbmexplicitvaildate.git question/behaviour/dfcbmexplicitvaildate
