Bug fix: HllSketch without HIP bounds calculations were way off.   The HllSketch eps() method was using the HIP_REL_ERROR_NUMER = 0.836083874576235 constant instead of HLL_REL_ERROR_NUMER = 1.04.  These are correctly used in Kevin's C code, but incorrect in Alex's HLL java code and everthing since. I am fixing it here but nowhere else.
