2.2.4  Transform a boolean expression as a list : exp2list

exp2list returns the list [expr0,expr1] when the argument is (var=expr0) or (var=expr1).
exp2list is used in TI mode for easier processing of the answer of a solve command.
Input :

exp2list((x=2) or (x=0))

Output :

[2,0]

Input :

exp2list((x>0) or (x<2))

Output :

[0,2]

In TI mode input :

exp2list(solve((x-1)*(x-2)))

Output :

[1,2]
