LongSpace
Provides spaces in which coordinates are expressed using Long values.
Note that the current implementation due to performance considerations
requires that the coordinates are clipped to 62-bit range. That is,
they should be >= -0x2000000000000000L and < 0x2000000000000000L

A helper method which efficiently calculates the unique integer in an interval [a, b] which has
the maximum number of trailing zeros in its binary representation (a and b are integers > 0).
This is used by the HyperCube implementations to find the greatest interesting square for
two given children.
