-- Function to return a table of fields and their offsets for the specified class name
-- params:
--    className: name of the class to get a structure definition for
--    namespace (OPTIONAL): namespace of the class to get a structure definition for
--    img (OPTIONAL): mono image in which to search for class, speeds up the process
--    static (OPTIONAL): set to true if you want static fields
-- Returns table setup like this:
-- k: 'field name', v: { offset, CE vartype, mono vartype }
-- Get values like: fields["fieldName"][1] for offset
