/**
 * Class Blueprint.
 *
 * The Schema blueprint works differently from the standard Illuminate version:
 * 1) ArangoDB is schemaless: we don't need to (and can't) create columns
 * 2) ArangoDB doesn't allow DB schema actions within AQL nor within a transaction.
 *
 * This means that:
 * 1) We catch column related methods silently for backwards compatibility and ease of migrating between DB types
 * 2) We don't need to compile AQL for transactions within the accompanying schema grammar. (for now)
 * 3) We can just execute each command on order. We will gather them first for possible future optimisations.
