-/**
-Base class that provides the implementation for RHexTree, which is just a thin
-template.
-
-An instance of this class can have up to eight 16-way prefix trees, with heights
-from 1 to 8. All the values are stored in the leaves. To find a value from a
-32-bit key, first the key is decomposed into 8 hexadecimal digits and then the
-prefix tree with height matching the number of digits in the key (ignoring zeros
-to the left) is traversed using the sequence of digits in the key as the
-indexing string. Offsets are internally used instead of pointers to allow
-instances to be placed in a heap shared between several processes.

-/**
-An associative array implementation optimised for the case where the keys are
-32-bit codes with spatial locality of reference. The values can be of any
-self-contained data type (that is, without destructor or clean-up functions).
-It allows multiple-readers, single-writer concurrent access from different

-individual key-value pairs.
