Changed implementation of logging macros.
We have observed some strange performance-related behavior as described here: https://stackoverflow.com/questions/29652787/adding-stringstream-cout-hurts-performance-even-when-the-code-is-never-called
This set of changes addresses this problem. The old macros would simply expand the logging code in place, whereas we now have logging functions and the macros call these. Overall I believe it is tidier.

Removed flush(Region) function as it's a bit trickier to implement with the new hash table, and it's not clear that we need it.

Added a second PagedVolume to the tests with much higher allowed memory usage. This makes more sense when testing random access, as low permitted memory usage causes disk IO to become the bottleneck.

This commit knocks about 30% off the run time of the sampler tests by using a more efficient check for whether we are near the edge of the chunk.

Commented out optimized path in sampler as it doesn't work now that we are using Morton ordering for the data in chunks. However, we can probably reinstate such a fast path if we give some thought as to how it should be done.
