Summary: Perl implementation of B+ trees

Description:
This is a Perl implementation of B+ trees. I have based this
implementation on a couple of sources. See the documentation of
Tree::BPTree for those details. A B+ tree is essentially an order
map from keys to values. Keys are multivalued so that there may be
more than one value per key. This implementation will enforce
uniqueness of keys, if requested.
