# This script makes it easier to handle relative neural connections in f1 genotypes when adding/deleting neurons.
# Usage:
#   perl add_neuro.pl <neuron_number> <f1_genotype>
# If not provided, the <f1_genotype> will be read from stdin.
# <neuron_number> is 1-based.

# TODO: handle bounds (1..N) of <neuron_number> and display a warning when exceeded
# TODO: test thoroughly
# TODO: consider joining with del_neuro.pl or including a common part - 80% of the code is the same.
