A new collection "mycollection.vermongo" will be created for each versioned collection and will store old document versions. You can change the name of the collection by passing a collectionName option to the vermongo function.

A collection helper "versions" is created to access old versions of the document.

On document removal, the current version is saved into the vermongo collection, and then a dummy new version is added with a special flag (as a column "_deleted" that equals to true).
