o Adding a 'db-stats' application for summarizing the contents of the database.

o Starting on make-bom. Extremely slow when using rdflib (~8 minutes), jena is very fast (~50 ms).

+* Change the arg parser to always allow a '--db' argument that defaults to './.eda-rdf'
+* Create an 'init' command similar to git init
+* Rename "schematic" to "project"? Schematic is .. schematic specific but many of the possible tools work on the BOM
+  and/or on the PCB so 'project' is probably a better term.
