Add 3rd level to Category hierarchy

[tchaddad]

From the Network meeting. Some desire to go down one more level on the Data categories hierarchy (level 3). Requires DWG to agree on level 3, and for records to be marked up.

Not sure if front end will need adapting.

We've added the 3rd level categories and from what I can tell, they are working in the UI with no additional fixes needed. The results are currently visible on the Dev server. Two things to note:

• One thing that is a bit confusing, is that we are not displaying top level record numbers - Physical, Biological, Human. This may bother people who like to do math :)
• A second thing that might confuse users is that the number of records for any given level may not be the sum of the numbers attached to levels below it. Rather, it is the sum of the records below it, PLUS the number of records with out any sub-classifications.

Once all these level numbers are reviewed and confirmed to our satisfaction, all that needs to be done to push this to production is to:

• use pgadmin to dump the "gpt_collection_member" table from dev, and use it to replace the equivalent table on production.
• restart Tomcat/Geoportal and Solr so that they pickup & index the changes

No other changes to scripts or other config files are necessary.
