Overview
--------

Add-on used mechanism of possibility to cancel execution of the running query from 
other thread. You call function passing DataSet that need to open or execute and time 
after which is necessary to show window of canceling. The window of canceling is a 
window with only one button with Cancel caption. You can press Cancel button to 
interrupt query. If the query take short time then the window of canceling will not 
be shown at all. The function returns control to the callable block only after query 
will be opened or executed, so you can use it as synchronous function.
