	Operations which require memory can use this to place requirements on the memory type for each MMO.

Detailed Description

The LegalityQuery object bundles together all the information that's needed to decide whether a given operation is legal or not.

For efficiency, it doesn't make a copy of Types so care must be taken not to free it before using the query.
