/**
* DBRecord is not intended to be used on it's own and should be implemented as a subclass for the specific model.
* However, in the case of quick and/or simple tasks, the class may be instantiated as a standalone object as such:
*
* $o = new DBRecord('TableName');
*
* If the DBRecord is implemented as a subclass which defines the table name, the constructor does one of two things
* depending on the data passed to it. If the argument is an array the argument is used as the initial record; otherwise
* the value is converted to a string and passed to the load() function as the primary key value.
*
* If the argument is absent, an empty record is instantiated.
*
* @param array|integer|string $o optional
