Generated points

[Jan]

We are now able to generate points instead of simply applying them as
a filter. This gives us a lot more possibilities. Changes done:

- A new map called who:zmcb_hfc (Zambia, Copperbelt - Health Care
Facilities) added to Geoserver. An SLD specified.

- A new Velocity template called pointSldTemplate.vm (src/main/
resources) created. The <StyledLayerDescription> content apparently
has to match the SLD specified by Geoserver.

- ChloroplethMapRequestGenerator.java:
Velocity.mergeTemplate() now refers to pointSldTemplate.vm instead of
chloroplethSldTemplate.vm. A pointSldTemplate resource and getter +
setter have been added.

- application.xml:
A new entry added: "who:zmcb_hfc".

- mapping.xml:
The "[Location].[OrgUnit3]" entry now has the value "who:zmcb_hfc"
inside "locationToLayerMap".
The "[Location].[OrgUnit3]" entry now has the value "LvlId" inside
"locationToGeocodedPropertyNameMap". To ensure that this value is
correct, simply open the <mapname>.dbf in Excel and chech the column
name.

NB! Deleting browser cache and restarting Tomcat may do the trick if
something that is supposed to work actually doesn't.
