## DefaultSequence.handle() method

Runs the default sequence. Given a handler context (request and response), running the sequence will produce a response or an error.

Default sequence executes these steps - Finds the appropriate controller method, swagger spec and args for invocation - Parses HTTP request to get API argument list - Invokes the API which is defined in the Application Controller - Writes the result from API into the HTTP response - Error is caught and logged using 'logError' if any of the above steps in the sequence fails with an error.
