moving up branch target
Update IO.R

adds start.row and stop.row parameters in HBase input format. I agree to assign copyright of that code to Revolution Analytics Inc., on the condition that it releases that code under the Apache 2.0 license.
merge from master with multiple bug fixes and changes in docs
Merge branch 'patch-6' of git://github.com/khharut/rmr2 into khharut-patch-6
start stop row feature for hbase format
remove workaround for caTools bug per @khharut comment #77

needs caTools 1.16
adjusted indentation
drop options when start.row or stop.row not specified
apparently did not balance paren right
indent
avoid native for attributeless lists

the tradeoff here is that slow R serialization could be necessary for
each element
rbind is sloooooow with many rows
cherry picked new benchmarks from fast-serde-1
merge from fast-serde-2
reshape2 seems only needed in an example
explain new args
byproduct of testing
rep_len is new to R3, so avoid here
this is always a local dir!
rep.int has some deadly interaction with t.list, replace with rep
don't fail if some out file missing
