Kernel::System::DynamicField::ObjectType::CustomerUser

=head1 DESCRIPTION

CustomerUser object handler for DynamicFields

=head1 PUBLIC INTERFACE

=head2 new()

usually, you want to create an instance of this
by using Kernel::System::DynamicField::ObjectType::CustomerUser->new();

perform specific functions after the Value set for this object type.
