New test file for review from axm1820
2 Python tests and one R test
Reservoir Sampling v1.
Added LRResult object to encapsulate results (instead of just Json).
Merge remote-tracking branch 'upstream/master'
Fix mystery NPE
Merge branch 'master' of github.com:0xdata/h2o
Fix a missing Nil in Shalala example.
Comments in code should be readable.
a little bit tricky. The quantile thresholds don't necessarily align to the bin boundaries.
So at the beginning and end, you have to add a percentage of the bin range, when you're creating a value for a quantile threshold..by making an assumption of linear distribution within the bin, which is true except for the last bin, which is potentially truncated from the expected bin size by _maxs[0]. So you want to change the linear distribution guess to the start of that bin, to _maxs[0]. Since you start with _mins[0], you don't have to worry about he other side. I eyeballed a bunch of cases, and this seems good. (The key thing: if the histogram is accurate, then just create the quantile estimate correctly from the histogram, accounting for these issues)

get sync'ed with current legal exec expressions
Raise the overflow limit to the Long limit

Exponents below 1e18 still fit in a 64-bit long.
Also check scaling overflow in fewer situations.
