Ordinal Indicators Failsafe

A new failsafe has been added to ordinalIndicators to allow for the entire library to be used within page layouts. Here's what's changed:

• All code within pageInfo/groupInfo has been wrapped in a conditional checking to see if the global variable content is undefined
  • If content is defined, the self-executing functions will run as expected
  • If content is undefined, the self-executing functions will return objects with null key/value pairs
