currently you can only define a single mapping per column. I think this is a bad restriction. I can't make up a very usefull scenario but since it just "silently" overrides the old mapping this could lead to a ugly mistake when debugging mappings. I see the following options:

* raise an error when the same column is mapped twice (don't allow duplicate mappings)
* no restrictions on columns
