Macro for setting up proxying for a specific DataVector<T> type.

In the xAOD packages that use DataVector classes, one must attach "collection proxies" to the container dictionaries. This collection proxy describes to ROOT how to navigate the contents of the DataVector container.

This is set up by adding a file called "src/dict/CollectionProxies.cxx" to the package (well, all files under "src/dict/" are taken into account in the end...), and for each DataVector type defined by a package, adding a line like:

ADD_DV_PROXY( MySuperContainer );

Macro for setting up proxying for a specific namespaced DataVector<T> type.
