Actually this class represents a hash that stores Beacon objects.
The current implementation is only a dummy.
Create a new Beacon collection.
Up to know only collections in a database (Data::Beacon::Collection::DBI) are supported,
so you must specify at least parameter
dbi or this method will croak.
Get a named Beacon.
Insert a named Beacon. This method works as 'upsert', that means you can replace or add a Beacon.
Remove a named Beacon.
List the names of all namad Beacons. Optionally you can ask for specific meta fields that must match.
