Merge pull request #63 from jmark99/bingest

Update the bulkIngest example to work correctly with Accumulo 2.0.x. Minor updates made to the documentation. The classes were refactored so the example will work correctly with 2.0 changes. Generation of test data was moved from SetupTable to BulkIngestExample (as in 1.10.x version). Prior to change, necessary data was not correctly being written to HDFS thereby preventing the BulkIngestExample class from finding information needed to generate the data. Closes #63.
