/*
** this function is called at each action (pushes, swapes, rotates)
** pointers to the stacks a and b are stored into two first element of list solution (because both lists a and b are not available from every functions, like sa() doesn't receive b in argument)
** the function access the list to fill a new element with three things :
** - the name of the action (sa, sp, rra, etc)
** - the stack a
** - the stack b
** like this :
**   name!a: nb nb nb nb nb!b: nb nb nb
** "!" are used to split, it will be turn into :
**   name
**        a: nb nb nb nb nb
**        b: nb nb nb
