Convert string_patterns to localist_patterns by counting the characters in
the string_pattern. The target representation (accessed via get_target) is
maintained by the conversion to ensure it has dimensions (layers have nodes)
for all relevant numbers.
some_ccc set_fixed 1
Instruct some_ccc to no longer modify (some_ccc get_target) to have
additional dimensions to provide an answer for previously unseen lengths; in
future return a zero localist_pattern for previously unseen lengths. Use to
maintain a model in fixed state after all “wiring” is complete.
some_ccc set_fixed 0
Revert to the modifying state.
