Transform a boolean expression as a list : exp2list

### 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]`
