    I changed the title to be more specific about the change and enabled the regex to be configurable (as well as the stopwords). There is an issue on the Jira about this (https://issues.apache.org/jira/browse/SPARK-5566) and the code passes the tests when I run it on my machine. The change is quite small, adds no dependencies and should be useful to anyone who wants to validate a NLP model using pipelines.
