/*
Tabs script based on data attributes for arbitrary target selection and limited structure restrictions

First, create a target out of any element (usually a div):
  -add class "zdw-tabcontainer"
  -add a unique id

Next, add content to the target:
  -each must be a div and a direct child to the target
  -add class "zdw-tabcontent"
  -add attribute "data-tab-content" to hold the unique (for this target) identifying string
  --for multiple selectors, use multiple "data-tab-content-selectorname" attributes

Then, add selectors:
  -they can go anywhere, inside or outside of the target
  -add class "zdw-tabset"
  -set attribute "data-tab-target" to the target's id
  -set attribute "data-tab-type" to "click" or "hover" to control how the tabs are activated
  -optional: set attribute "data-tab-selector" to some string if you wish to have more than one tabset for the same selector

Finally, add tabs:
  -they must be descendants of their respective tabsets
  -add class "zdw-tab"
  -optional: set attribute "data-tab-selection" to a unique (for this selector) identifying string
  --this will be compared to "data-tab-content-selectorname" in the target
