Removing unneeded file
Fixed problem with processing when mongoexport gives floating point values as
scientific notation.  This required a Pig user defined function, written in
Java.  The JAR file is called in clean-numerics.pig, after all the merge and
reduction steps, but before averaging (since that's a true numeric function,
not just a database operation).
