CREATE NEW MOUSE:
-----------------
new Mouse(async mouse => {
    await mouse.func(...);

    // also can be inside conditionals and loops
    // e.g.
    if (cond ..) {
        await mouse.func(...);
        ...
    } else {
        await mouse.func(...);
        ...

CREATE NEW ACTION:
------------------
let action_name = async mouse => {
    await mouse.func(...);
    ...
    return mouse.ENDFLOW;

CALL A CLAMP BLOCK FUNCTION:
----------------------------
...
await mouse.func(async () => {
    await mouse.func(...);  // non clamp block function
    ...
    return mouse.ENDFLOW;
});

RUN ALL MICE:
