LDA Example: Modeling topics in the Spark documentation

	/*
	This example uses Scala. Please see the MLlib documentation for a Java example.

	Try running this code in the Spark shell. It may produce different topics each time (since LDA includes some randomization), but it should give topics similar to those listed above.

	This example is paired with a blog post on LDA in Spark: http://databricks.com/blog
