EventWriter loads the information in each 'Event' into the database.
While loading multiple values of the same element into a single DB column, the
multiple values are delimited by MULTIPLE_VAL_DELIM.
When an element and its attribute are loaded into a single DB column, the
value and the attribute are separated by a DB_ATTRIB_DELIM.
When using delimiters to append values, if the values already have the
delimiter, the delimiter in the value is escaped as in URLs.
Values for the ' ' block are loaded with each parm name and parm value
delimited with the NAME_VAL_DELIM.
