=head1 CHANGES

v0.11 introduces the lesion method, png support in the draw module and datasets.

v0.12 fixes a bug in reinforce.pm & adds a reflector in feedforward->run to make $network->run($dataset) work.

v0.13 introduces the momentum learning algorithm and fixes a bug that allowed training to proceed even if the node activation function module can't be loaded

v0.14 fixes momentum and backprop so they are no longer nailed to tanh hidden units only.

v0.15 fixes a bug in feedforward, and reduces the debug overhead

v0.16 changes some underlying addressing of weights, to simplify and speed
