Template for Finsignia compliant gen_server.

Used with rebar create subcommand we can generate a initial gen_server
that complies with Finsignia internal coding standards/style guidelines.

To generate run:
% rebar create template=finsrv server_name=server_name_minus_srv \
    description="Manages connections to database...." \
    author_name="Your Name" author_email="user@domain.com"
