a - defines the action you want the function to perform. 
o - the object in question. 
c1 - the name of the first class 
c2 - the name of the second class 
Possible actions are:
swap - replaces class c1 with class c2 in object o. 
add - adds class c1 to the object o. 
remove - removes class c1 from the object o. 
check - test if class c1 is already applied to object o and returns true or false.
