Partial Response PSR-15 Middleware

Purpose

Google in their Performance Tips for APIs, suggest to limit required bandwidth by filtering out unused fields in response. Their APIs support additional URL parameter fields which asks API to include only specific fields in response.

This project wraps php-value-mask library (which provides filter parsing and filtering) in PSR-15 middleware, which can be used with standards compatible frameworks.

See php-value-mask project for more details on filtering syntax.
