In the Probe Alias Browser there should be an option
when a user right clicks on a probe point or variable
to track this value. Clicking this should
automatically create and run a new script that will
watch that specific value. The user never needs to see
the contents of this script.
For function calls, it could simply count the number of
times the function is called each second. For
variables it could print out the value of the variable
every time it is hit, as well as counting the number of
times it is called each second.
