2.6-SNAPSHOT map/array behavior does not correspond with README

[ldcasillas-progreso]

The README.md currently in the version-2.6 branch states the following:

Avro Maps will be read in and converted to Java Maps. Avro Arrays will be read in and converted to Java Lists.

But looking at the AvroToCascading.java version currently in the branch (from commit 70d9562), this is not true. Both Avro maps and arrays will be read in and converted to Cascading Tuples. For example, an Avro map will be converted to a Tuple with keys in even indexes and values in odd indexes.

The corresponding code in the version-2.5 branch does conform with the README.md. So which is right, the README or the code?

@vmagotra - I wonder if this is due to an an aborted merge with some changes @ccsevers was working on? I think we'd want to try to use maps and lists if possible, as that would facilitate the nested data structure filtering work we'd been discussing.
