This class represents a reference (or \*(L"join\*(R") to a MongoDB document.
In MongoDBx::Class, references are expected to be in the DBRef format,
as defined in <http://www.mongodb.org/display/DOCS/Database+References>,
for example (this is a \s-1JSON\s0 example):
.PP

the following attributes are provided:
.SS "ref_coll"
.IX Subsection "ref_coll"
A string representing the collection in which the reference document is
stored (translates to the '$ref' hash key above).
.SS "ref_id"
.IX Subsection "ref_id"
A MongoDB::OID object with the internal \s-1ID\s0 of the referenced document
(translates to the '$id' hash key above).
.SH "METHODS"
.IX Header "METHODS"
Aside from methods provided by MongoDBx::Class::EmbeddedDocument,
the following methods are provided:
.SS "\fIload()\fP"
