Basic - The "it just works" scenario
Activate _tics.js by calling the page() function. Run the events() function if you want to track form fields.

More features - The "couldn't you just do this?" scenario
The library includes three specialized functions. The functions are activated when elements are decorated with the attribute data-val-analyze-custom. The included functions are:
get the value of a field (getValue)
get the relative change within a field (getRelativeChange)
get the position of a clicked link in a list of banners or in a menu (getItemInSection, combined with the attributes data-section and data-item)

Customization -The "extra special for you" scenario
The getValue, getRelativeChange and getItemInSection functions are included in _tics.js. But you can also add your custom function by appending them to the library. Use your favorite library for traversing the DOM if you like.
If you want to override or hijack one of the existing functions, just call the add function and use the same name as one of the built in functions. You can also add any event that is not covered by the built in features.
