Remarks
Checks if this FilePermission object "implies" the specified permission. More specifically, this method returns true if: p is an instanceof FilePermission, p's actions are a proper subset of this object's actions, and p's pathname is implied by this object's pathname. For example, "/tmp/*" implies "/tmp/foo", since "/tmp/*" encompasses all files in the "/tmp" directory, including the one named "foo". Precisely, a simple pathname implies another simple pathname if and only if they are equal. A simple pathname never implies a wildcard pathname. A wildcard pathname implies another wildcard pathname if and only if all simple pathnames implied by the latter are implied by the former. A wildcard pathname implies a simple pathname if and only if: if the wildcard flag is "*", the simple pathname's path must be right inside the wildcard pathname's path; if the wildcard flag is "-", the simple pathname's path must be recursively inside the wildcard pathname's path. "<<ALL FILES>>" implies every other pathname. No pathname, except for "<<ALL FILES>>" itself, implies "<<ALL FILES>>".
