Template Directory

[NadavK]

First, thanks for an excellent package! It was (fairly) easy to install, and bam! Instance maps!
I would like to point out that adding django_admin_geomap to INSTALLED_APPS removes the need edit ``TEMPLATES```.
I find this easier/robust because I was not able to add a template directory that supported both dev and deployment environments.

Thanks again!

Agree, using INSTALLED_APPS is preferable. Editing TEMPLATES present by "historical reasons" :)

I will fix the docs and example.
