// Chunks are stored in the following array which is used as a hash-table. Conventional wisdom is that such a hash-table
// should not be more than half full to avoid conflicts, and a practical chunk size seems to be 64^3. With this configuration
// there can be up to 32768*64^3 = 8 gigavoxels (with each voxel perhaps being many bytes). This should effectively make use
// of even high end machines. Of course, the user can choose to limit the memory usage in which case much less of the chunk
// array will actually be used. None-the-less, we have chosen to use a fixed size array (rather than a vector) as it appear to
// be slightly faster (probably due to the extra pointer indirection in a vector?) and the actual size of this array should
// just be 1Mb or so.
