docs: outerHeight : outerHeight(el, includeMargin)
  Returns the outer height (height + padding [+margin]) of an element as an
  integer. Supports IE8+.
  
  If `includeMargin` is true, then margins will be part of the computation.
  
  var outerHeight = require('dom101/outer-height');
  var height = outerHeight(el);
  var fullHeight = outerHeight(el, true);  // include margins
