/**
* Implementation of HyperLogLog++ described in
*
*
* http://static.googleusercontent.com/external_content/untrusted_dlcp/research.google.com/en/us/pubs/archive/40671.pdf
*
*
* Brief HyperLogLog++ Overview
*
* Uses 64 bit hashing instead of 32
* Has two representation modes: sparse and normal
*
* 'normal' is approximately the same as regular hyperloglog (still uses 64 bits)
*
* 'sparse' handles lower cardinality values with a highly accurate but poorly scaling
* strategy and leverages data compression to compete with 'normal' for as long as possible
* (sparse has the advantage on accuracy per unit of memory at low cardinality but quickly falls behind).

* Encode the sp length idx and, if necessary, the run length.
*
* Start with the 64 bit hash as x.
*
* Find all the bits that belong in the first sp (roughly 25) bits. (This is idx')
* Get rid of the first p (roughly 18) bits of those. (Those were idx (not prime))
*
* If all the remaining bits are zero then we are going to need to find and encode the
* full run length of leading zeros, but this only happens once in 2 ^ (sp - p) or roughly
* 2 ^ 7 times.
*
* If at least one of them is not zero, then since the run length is determined by bits
* after p and the idx' contains the first (sp - p) bits of those, then just by putting idx'
* in the encoding, we will also be giving it all the information it needs to find the run length.
*
* The relationship looks like this:
*
* ******************************************************* <- hashed length of bits
* | p bits = idx || look for leading zeros here |
* | sp bits = idx' |
* | all 0s? |
*
* If we have idx', we could theoretically scan it (as per zeroTest) when unencoding and therefore know whether
* to look for the extra run length information. However, for now we have followed the authors of
* the paper and put this information in a flag bit at the end of the encoding.
*
* Based on this flag, we know whether to adjust for the missing run length bits. We could also
* use this flag to compress all the zeros in "| all 0s? |", but saving a byte or so once in 128
* times is less than the 120 bits spent on the flag elsewhere. Of course, after compression, the losses
* are not quite so large either way.
*
* The encoding scheme now looks like:
*
* ********************************* <- smaller length of bits (half, but not to scale)
* | empty || sp bits ||F|
* | p bits || has 1 ||0|
*
*
* or if the run length was needed (ie 'all 0s?' was indeed all 0s):
*
* *********************************
* | sp bits || run len ||F|
* | p bits || 0s | |1|
*
*
* The other notable encoding feature is the inversion of the run length, which just lets the lists
