 * I have been working on trying to make a widget that has dynamically printed checkboxes
   in the front end and controls in the admin section.
 * The problem I’ve had with both of these is that as soon as I use PHP functions
   to initialise an object of a class in another file in order to use that object’s
   functions the html execution ceases, I get either the “white screen of death”
   or I get all the html executed up until that point.
 * Can a class that extends WP_Widget not use PHP in this way?
 * What could I do instead? (will provide code later, catching a bus).
