CouchDB Database Ensurer

The `couchdb-ensure` package provides a focused Node.js utility for managing CouchDB database existence. Its primary function is to check if a CouchDB database at a specified URL already exists and, if not, to create it. This makes it an ideal tool for initial application setup, automated testing environments, or any scenario requiring a guaranteed database presence before operations begin. The current stable version is 2.1.0, released in October 2021, indicating a mature and stable codebase with an infrequent release cadence, typically driven by updates to its core dependencies like the `nano` CouchDB client. Unlike full-featured ORMs or database management tools, `couchdb-ensure` differentiates itself by its single-purpose API and a convenient command-line interface (CLI) for rapid database initialization, providing a lightweight and efficient solution without unnecessary overhead. It primarily utilizes CommonJS for module exports.
