> Clean up the code in org.apache.mahout.math.list, including some testing and cleanup
of some things that it calls.
> This includes:
> 1) More features in the Velocity code generator, including code to avoid generating a
shadow of a checked-in file, and code to allow explicit suppression of individual outputs.
Also an extra macro or two to make the template neater in some cases.
> 2) The stack of code from AbstractList to AbstractXxxList to XxxArrayList generated with
templates. AbstractCollection eliminated. ObjectArrayList preserved for now until the maps
can be weaned from it.
> 3) Removed 2 broken functions from the Sorting class.
