* a hard limit.
* @param cpucost The allowed cost in terms of cpu to determine the
* information in the fields. The number mean the amount
* of instructions allowed is 10^cpucost and is a suggestion only.
* The default value of 6 means that about a million
* instructions (10^6) are allowed. This is useful for
* expensive fields like md5 or thumbnails.
* @param requiredfields The names of fields or groups of fields that should
* be retrieved regardless of cost.
