/**
Attaches stand-alone container with editable-form to HTML element. Element is used only for positioning, value is not stored anywhere.<br>
This method applied internally in <code>$().editable()</code>. You should subscribe on it's events (save / cancel) to get profit of it.<br>
Final realization can be different: bootstrap-popover, jqueryui-tooltip, poshytip, inline-div. It depends on which js file you include.<br>
Applied as jQuery method.
