Document classes

[adam-lynch]

It would help if the documentation outlined all the classes added to elements. I want to do some cool stuff. Also personally, I found the transitions were too long and didn't realise it was just a CSS transition :)

I will add instructions regarding the css selectors ASAP...
In the meanwhile, a short brief of the classes involved in the drag&drop process:
'hidden-layer' : this class is added to the original dom element in order to hide it while dragging occurs.
'visible-layer': this class is added to the clone of the dom element while dragging occurs
'originialID-lmddClone': the clone gets the original element id + '-lmddClone' prefix (needed in case you have id related css rules)
'lmdd-mirror': class added to the 'mirror' element while dragging
'lmdd-shadow':class added to the 'shadow' element while dragging
