Simple example for writing random data to Accumulo. See docs/examples/README.batch for instructions. The rows of the entries will be randomly generated numbers between a specified min and max (prefixed by "row_"). The column families will be "foo" and column qualifiers will be "1". The values will be random byte arrays of a specified size.
