1) Handling Null pointer Exceptions for EntityPubCount, EntityGrantCount and EntitySubOrganizationTypes
2) Removing the dependency on vis_mode parameter in the server side code. The class the individual belongs to is retrieved using vitroRequest.getWebappDaoFactory().getIndividualDao().getIndividualByURI(IndividualURI).isVClass(ClassURI)
3) On the client side, the vis_mode parameter is set(from the value passed on by the requesthandler) to differentiate between personURL and SubOrganizationTemporalGraphURL on drill down.
4) Added entityComparisonErrorActivator.ftl to handle edge cases (if the resultset of the queries is NULL)
2. Implemented the ellipsis feature for the legend row (containing the bar & label for selected entities). If the label is too long it will try to fit in the provided space & append "..." at the end.
1) Added entry for entity_grant_count in visualizations-beans-injection-fm.xml
2) Styling changes in layout.css -- changed the styling for buttons.
3) util.js -- Removed hardcoding of URLs see NIH VIVO 1618 and 1619
4) Made queries for EntityGrantCount, EntityPubCount and EntitySubOrganizationTypes more generic. Added Export as CSV functionailty for EntityGrantCount
