New egg: mdh

[felix . winkelmann]

Hi!

This is to announce the "mdh" egg, an interface to the C++ API of O'Kane's
MUMPS database. The concepts behind it were presented by Luke at the
CHICKEN Coding Jam and produced quite some interest. MDH is a very
easy to use multidimensional key-value store. The code is included in
the egg, the only external dependency is libpcre.

Documentation can be found here: http://wiki.call-cc.org/eggref/5/mdh
(or of course at api.call-cc.org).

Note that this is a first release. It seems to work fine, but has not been
heavily tested with regards to scalability and performance. There are a few
parameters than can be tweaked once there exists more experience with
using this database.

Many thanks to Luke K. for inspiration and fruitful discussions regarding
a suitable Scheme API.
