Feature Request: Endpoint to download TSV File templates matching schema headers

[joneubank]

Lectern schemas are structured as they are to work with TSV data files. To facilitate the creation of compatible data files Lectern should have an endpoint that can generate a TSV template file for any schema (or for every schema in a dictionary).

A TSV template file for a schema includes a header row with the field names from a schema separated by tabs. The file should be named with the schema name, ie. schema_name.tsv.

All templates for a dictionary can be generated following this pattern and then provided in a single zip file for download. The zip file should be named with the dictionary name and version number.

Detailed Description

Two endpoints needed:

1. GET /dictionaries/:dictId/templates - Download all schema templates for dictionary in zip file.
2. GET /dictionaries/:dictId/schemas/:schemaId/template - Download template for an individual schema
