Added three HOT templates that demonstrate:

1. Multi-server RHEL 6.5 Wordpress application with associated
  Neutorn networking. Database resides on a Cinder volume. Web
  Server is accessible via a floating IP. Also create private
  Neutron network, subnet, and router, and adds Security Group
  rules.
2. Same as #1 but uses F18 image instead of RHEL 6.5.
3. A Neutron-only template that creates a public network and subnet.
 This template can be used in conjunction with #1 or #2 to lay
 down public network infrastructure including provider network for
 external/public floating IP addresses on a private network.
