Rate Limit issue

Hi,

I am facing rate limit issue when trying to fetch data for more than 200 files at once.

com.box.sdk.BoxAPIRequest : Retrying request due to transient error status=429 body=
{"type":"error","status":429,"code":"rate_limit_exceeded","help_url":"http:\/\/developers.box.com\/docs\/#errors","message":"Request rate limit exceeded, ple
ase try again later","request_id":"fydhw5gxf2sl55om"}

For 200 files, it is smooth but after that it gives this issue.
