New version with automatic conversion of keys and values from char to string if a string class is available.

See thread on Discourseabout a dictionary class:

I attach my current attempt at implementing it. It requires a keyHash function to be implemented and so far I use:

## -*- texinfo -*-
## @deftypefn {} {@var{hashval} =} keyHash (@var{val})
## Calculate a uint64 hash value of the variable @var{val}.
## @seealso{keyMatch, dictionary}
## @end deftypefn

function hashval = keyHash (val)

  hashval = hash ("sha1", jsonencode (val));
  hashval = typecast (hashval(1:8), "uint64");


A string class is nearly essential here otherwise make sure to only use char scalars as keys or values. I tested the code with the string implementation from octave-tablicious.
