Implementation of DataPackageCount
Implementation of a statistics package

Includes count of packages by journal
Main class to run journal statistics
Auto-generated test class from netbeans. Doesn't do anything yet
remove '/' to increase template matching for testing.
don't check @qualifier
fix indents
create root node first

root node template makes <resource> tag and calls <xsl:apply-templates>
within.
make generic template to get identifier element
refactor code to find <identifier>

There should only be one DOI, so no need to call loops
move "dim:dim" template start/end

variables can be declared outside of this template.
fix indents
handle finding non-dim data for datacite

template parse_mets finds datacite data that is not stored in DIM.
add some comments

Classes for Dryad core model API
Refactored to use Dryad core Model API
