use the shared fp_format()
add some tests for plotting parsed size and remove time
HEX-1945: Fix typo in RebalanceDataSet (make the same as h2o-dev).
Note: This looks wrong to me, still.

Criterion for sparsity should be
sparse_len * 32 < dense_len, and not: sparse_len < 32 * dense_len (always true!)

fix some errors and move it to multi-machine only
more time
HEX-1945: Fix logic to determine whether the chunks are to be treated as sparse.
HEX-1945: Add asserts in sparse() call.

remove the biggest case from the parse/remove case ..was getting poll timeout
add another variation of bad result as ok, to the iris kmeans
change IP addresses for the cpu/mem perf results
Added double compression test testing mantissa range which does not fit into signed long.
HEX-1945 fix. TransFVec had bug inflate_impl -> forcibly setting length and sparseLength at the end makes invalid sparseChunks (sparseLen == len, but fewer stored values)..
Fixed error reporting in Reblance task (the map in Reblanace is "inverted" - running on the target chunk instead of source chunk, target chunks is always C0LChunk so no reason to report that, we're really interested in the srcChunk which caused the error)

Also removed mostly broken error reporting in NewChunk.values.
HEX-1945: Remove assertions.
PUB-1045: Print full precision for percentile values in Summary2, not just 2 digits.  Was losing all accuracy for values < 0.01
Change time format from hh to HH so 24-hr time is printed properly.
get rid of dataset with matching col names
PUB-702: Compute Gains/Lift table for binary classifier.
Merge branch 'master' of https://github.com/0xdata/h2o
increased #nodes, heap
