---------------------------------

[~chris.roberts] would the toString with maxLineWidth work for your use case?

 In the case where I am printing the results of Statistics.corr(RDD[Vector]) I get a bunch
of doubles with ~19 characters, when I only realistically have at most 5 significant digits.
 I would love to be able to pass in a format to limit the printing out of extraneous digits.
