The configuration file for the DHCP server is made up of nested declarations. These declarations
can be sorted in two groups: containers and parameters.
Containers are the declarations that show as links in the main DHCP configuration page.
Containers are the ones that can be nested, they themselves may contain other
containers or parameters.
The containers currently supported by NameSurfer are group, host, subnet, shared-network and pool.
Parameters show as normal text, and they can not be nested.
The separation of parameters and containers is necessary to make the
selection of a new declaration easier.
