change output from mesh parser from db to file

[saschaben]

Rather than writing data directly to the DB, have the parser output SQL statements to file(s).
This will let us get around including any DB driver at all, as well will make it easier to debug/test this damned thing.

[jrjohnson]

Do we need to preserve the database write functionality or can that be abandoned completely in favor of SQL output?

[saschaben]

Hmm. good question. Can a case be made for allowing either/both?

(short answer: No.)

Fixed in ilios/mesh-parser#1
