Create a comprehensive LFE tutorial

[Duncan McGreggor]

Moved to: cnbbooks/catalog#14

Following up on the "Basic Tutorial" in issue #40, this ticket aims to take it to the next level with the following:

• providing an introduction to Lisps in general for folks that have no background there
• providing a gentler introduction to Erlang than that provided in the basic tutorial
• identifying holes or "weak spots" in the Basic Tutorial where new-comers have struggled, encountered ambiguities or difficulties, etc.
• examining good tutorials from other languages
• putting all of this together for a v2 of the tutorial

Part of epic #75
