.parse(source, database: nil, resolver: nil, fetcher: nil, source_file: nil) ⇒ Object

Parse source (a CDDAL string) into a Opencdd::Database.

Options:

database: - existing Database to merge into (default: new)
resolver: - Opencdd::Cddal::Resolver for module imports
          (default: a fresh Resolver with default fetcher)
fetcher:  - shortcut; if supplied, wraps in a new Resolver
source_file: - path/URL the source came from. Used for
          diagnostics and for resolving relative imports.
