     * @param acl the access control policy to apply to the uploaded file
     * @param bucket the vzaar bucket that has been allocated for this file
     * @param policy a Base64-encoded policy document that applies rules to
     * 	file uploads sent by the S3 POST form. This document is used to authorise
     * 	the form, and to impose conditions on the files that can be uploaded.
     * @param expirationDate s Greenwich Mean Time (GMT) timestamp that
     * 	specifies when the policy document will expire. Once a policy document
     * 	has expired, the upload will fail
     * @param accessKey the vzaar AWS Access Key Identifier credential
     * @param signature a signature value that authorises the form and proves
     * 	that only vzaar could have created it. This value is calculated by signing
     * 	the policy document
