+** updated by Jeff Richardson
+** Updated to use strict,
+** IE 7 has a "bug" It is returning undefined when trying to reference string characters in this format
+** content[i]. IE 7 allows content.charAt(i) This works fine in all modern browsers.
+** I've also added brackets where they weren't added just for readability (mostly for me).
