== SYNOPSIS ==
DO NOT USE THIS CLASS DIRECTLY! use via esmith::DB.
my $key = $record->key;
my %properties = $record->props;
my $value = $record->prop($prop_key);
$record->set_prop($prop_key, $prop_val);
my $value = $record->delete_prop($prop_key);

== DESCRIPTION ==
This class is a general interface to individual records in esmith::DB databases. It should not be used directly, but rather esmith::DBs should hand you esmith::DB::Record objects.
Each subclass of esmith::DB will also have to subclass and implement an esmith::DB::Record subclass.
=== Virtual Methods ===
==== key ====
my $key = $record->key;
Returns the $key for this $record;
==== props ====
my %properties = $record->props;
my $num_props = $record->props;

==== set_prop ====
my $value = $record->prop($property);
$record->set_prop($property, $value);
Gets/sets the $value of the $property in this $record.
set_prop() will die if the database is read-only.

my $value = $record->delete_prop($property);
Deletes a $property from the $record, returning the old $value.
delete_prop() will die if the database is read-only.
==== merge_props ====
$record->merge_props(%properties);
Adds the %properties to the $records existing properties. Any new keys will be added, any existing keys will be overwritten.
merge_props() will die if the database is read-only.
==== reset_props ====
$record->reset_props(%properties);
Replaces the $record’s properties with the contents of %properties. Any old properties will be deleted.
reset_props() will die if the database is read-only.
