Detailed Description

template<typename ObjectType, typename Operation>
class pat::PATUserDataMerger< ObjectType, Operation >

Assimilates pat::UserData into pat objects.

      This expects one input:
src:               The data to add to the objects that get passed to this
                   object, which are ValueMaps to some type (like UserData or double).

This will be called from PATUserDataHelper to handle the templated cases
like UserData or double. PATUserDataHelper will then add all the instantiated
cases.
