Add Three Examples

First three examples, and the skeleton for the fourth.  All have been left unstyled until there is a consistent motif in the documentation.  Similarly, because the fourth example deals with changes to the default styling, we should delay fleshing it out until we know what styling would both look good with the page styling as well as radically different from the defaults.

Last commit fixes a bug in the relative path for importing bootstrap. Without the line change, grunt will not build it.
