Given evidence for an assembly to be loaded, this method evaluates the code group by first checking the membership condition against the specified evidence. If there is a match, this method returns a policy statement for the code group, including evaluation of child code groups.

The operation of this method is as follows:

If the membership condition does not match the specified evidence, return null; otherwise, set the permission set to be returned (P) equal to the code group's policy statement and continue. For each child code group, resolve the code group with the same evidence; if the result is not null, return that policy statement. If no child code group matched, return P (the parent's policy statement).
