#1 Error streaming in multi-word vertices

[Ernest Foster]

If a multi-word concept, relation, or actor is in a
graph, then the graph cannot be streamed back in from a
file. Thus, if one were to create a graph which
contained the concept "Central Processing Unit" then it
would be streamed out to a file without issue but could
not be streamed back in. This almost definitely
results from a stream in which is stopping at the first
whitespace instead of reading until the end of line.
