FEATURE/DOC REQUEST: Example with a DB middleware

[pkphilip]

Love your framework but would really appreciate more documentation - especially for the use case with the following:

• A backend database connection (PostgreSQL, MySQL..etc)
• Database connection pooling
• Templates (Freemarker, Mustache etc) with a common layout + page specific layout
• Session handling I love the way the Amber Framework has a full video explaining this. If you need help with the documentation, do let me know.
