Jul, 2014 The code in this file handles thinning for DataVector and IAuxStore objects. Support for other types may be added by providing additional overloads for copyThinned1.

There are two variants: copyThinned and @ copyThinnedConst. The former returns a non-const pointer, and the latter returns a const pointer. Only the const variety may be used with a DataVector instance.

In the signature of copyThinned1, the container is passed twice: once as a reference and once as a pointer. This allows one to use overload resolution on the pointer argument to select the proper overload, while still being able to get the derived type of the container via template binding to the first argument. See the declarations below for concrete examples.
