Added new Gene class as it was getting difficult to avoid this concept in a bioinformatics application.
Changed getter method names to start with 'get' so that the JSP EL could retrieve the properties from the Status objects.
Integrated the Gene concept into the OrthologCache and DAO classes.
GeneController and gene page now deals with Gene objects rather than purely GeneIdentifiers. This makes life a little easier.
Added curation and project statuses into gene and disease pages.
