Setting probability for popunder to appear
in percents. 10 means there is a 10% chance
of advertisment to appear on every page view
(excluding sittuation when user is marked).
It means popunder should appear approximately
on every 10th page view, but thats random,
so don't count on consistency

set_exit method allows you to give visitor option
to skip advertisment and continue to requestet page
If set to false, then visitor will have to wait whole time
specified by set_timer method, if visitor will try to
refresh page, timer will be reset and start over again
(class uses session to maintain that)

There is an opton to mark visitors that already
viewed advertisment, to not bother them too often, using cookies.
The "not bothering" time depends on time set using
set_period() method in seconds,
by default it is 1 day, but you may change it if you wish.
If you choose not to use visitor marking
(by default it is on, but you can disable it using method below)
then popunder ads will appear based on specified probability
on every pageview, which could be pretty annoying
if probability is high

callback function is used to gather statistic
about which advertisment was shown and was it
skipped by user, or fully viewed
Callback function needs to be declared before
passing function name to class
and it must accept 2 parameters
1. parameter - ID of advertisment you provided
when adding advertisment to rotation
2. parameter - bool whether advertisment was skipped
by visitor. False means visitor didn't push
skip advertising button/link
