count_characters_conversion_impl
================================

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.

set_fixed
=========

	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.
