Initial commit - parsing args like Tool does. But may not end up using this eventually.
Works now for both local and hdfs modes - except one warning for bad params --hdfs and --local during startup
Tests should now run during assembly
Adding an hdfs option to scald-repl.sh. Works, but still need to clean up a bad param warning.
Merge branch 'scalding-repl' of https://github.com/sriramkrishnan/scalding into scalding-repl
Merge remote-tracking branch 'upstream/develop' into develop
Now able to pass --hdfs or --local, and also hadoop params such as "-D foo=bar"
Updating to ignore warnings for passing params that the MainGenericRunner doesn't care about (such as --local)
Added implementation of PartitionSource with tests. Notes:

* For Cascading documentation on PartitionTaps, see: http://docs.cascading.org/cascading/2.5/userguide/html/ch08s07.html
* Implementation is very similar to existing TemplateSource
* User can pass in delimiter + pathFields, TemplateSource-style, OR a custom Partition. I've written tests for both
* Unlike a TemplateTap, a PartitionTap can be read from as well as written to. I haven't implemented this
* I wanted to add a flag to automatically discard the pathFields from the output tap prior to writing, discussed here: https://groups.google.com/forum/#!topic/cascading-user/w24BMQ6ZG10. Nobody replied so I've removed this functionality for now
Whoops, got path depth wrong. Always 1
Moved into correct folder path
