Templatize mockups/examples

[oubiwann]

We need to perform the following templatization tasks:

• Convert HTML to Exemplar S-expressions
• Split S-Expressions into Modules
• Convert HTML mockups to Erlydtl (Erlang Django Templates)
  • Added erlydtl as a dep
  • Create structure template with all page blocks defined
  • Create base template that inherits from structure template -- this will have the page layout HTML common to all pages
  • Use this base template to convert HTML mockup pages
    • Convert top-nav - Add proto-template with top-nav #5
    • Convert right-nav - Add right-nav (light) #4
    • Convert left-nav - Add left-nav (dark)  #3
    • Convert single-colume page template - Add single-column page template #6
    • Convert landing-page - Add below-the-fold doc categories on docs main page #2
    • Convert 2-column page - Integrate left nav into 2-column page mockup #9
    • Convert 3-column page - Integrate left + right nav into 3-column page mockup #10
  • Demonstrate generation of static content from erlydtl templates

This ticket is part of epic #66
