Modules
A DualMap is simply a dual-entry map struct that allows you to reference pairs of data using both, a key or a value. In a DualMap you can look up a value from its key or a key from its value.
A DualMap.WCN is like a DualMap but with column names. So you need to reference columns (called master keys) in most of the calls.
