A method would be handy which would take an object implementing a model interface, create a vertex and copy the properties into the returned proxy. Something like JPA's persist().

USE CASE: E.g. JAXB creates an object and fill it with data. We don't want to create a data transfer method for each Model just to copy the properties. This should automate it.
JAXB is heavily used in WindRide's codebase for server migration.
