        This method constructs a ForeignKeyColumnRefs object that includes the columns named in the input list, as well as the referenced table and column names. Note that this method does not update the schema stored on disk, or create any other supporting files.
        tableSchema - the schema of the table that the foreign key will be added to
        refTableInfo - the table that the foreign key will reference
        constraintDecl - the parsed constraint declaration describing the foreign key
        an object describing the foreign key
        SchemaNameException - if a column-name cannot be found, or if a column-name is ambiguous (unlikely), or if a column is specified multiple times in the input list.
