  === Supported Queries
  
  The SPARQL-Gremlin transpiler is currently an on-going effort with an aim to cover the entire SPARQL 1.1 query feature
  spectrum, however we currently only support translation of the SPARQL 1.0 specification, especially _SELECT_ queries.
  The supported SPARQL query types are:
  
  * Union 
  * Optional 
  
negative.code: * A SPARQL Union query with un-balanced patterns, i.e. a gremlin union traversal can only be generated if the input
  SPARQL query has the same number of patterns on both the side of the union operator. For instance, the following
  SPARQL query cannot be mapped using Gremlinator, since a union is executed between different number of graph patterns
  (two patterns `union` 1 pattern).
