usage: dspace journal-stats
 -f,--from    Begin Date
 -h,--help    help
 -j           Journal Name (required)
 -t,--to      End Date

DCDate is used for date parsing, accepts '2014', '2014-01-01', or full ISO8601 formatting


$ /opt/dryad/bin/dspace journal-stats -j "Heredity"
$ /opt/dryad/bin/dspace journal-stats -j "Heredity" -f 2013-01-01 -t 2013-12-31


By default, the command-line tool will run all the statistics listed in Initially there are a few. The framework is designed to be used in other configurations beyond command-line interaction. Individual statistics are subclasses of and are templated for a single return value. This value may be a number (simple count) or a Map (e.g. for data packages submitted by month)
