establish the  various

 It is important to consider the data being imported to TinkerGraph with respect to `defaultVertexPropertyCardinality`
 setting.  For example, if a `.gryo` file is known to contain multi-property data, be sure
to set the default
 cardinality to `list` or else the data will import as `single`.  Consider the following:
