[boost] [mpl]suggested addition in vault/cppljevans/mpl/child_i_depth_j.zip

child_i_depth_j allows the traversal of a tree of applications.
It's useful for accessing, for example, the i-th superclass of
the results of mpl/fold, as demonstrated by the test file:

   libs/mpl/test/child_i_depth_j_test.cpp

included in the zip file mentioned in the subject line.

Could this be added to mpl?  Is there something I could do
to facilitate this addition?
