Generate a database schema diagram given eHive-style database URL
Some GraphViz design ideas borrowed from (or shared with) @muffato's https://github.com/Ensembl/ensembl-hive/blob/master/scripts/dev/sql2rst.pl
But the input interface is different: sql2rst.pl reads schema information from a properly annotated SQL script. This project reads schema information from an existing SQL database.
