Removed unecessary defines from utils.h. yruba clean does not
delete docs anymore.
Corrected bug in feedforward network init, it would lock into an
infinite loop if no node could be resolved on the first
pass
Removed the "gray" node op because it is the same as green .33 red
.33 blue .33 (albeit slower)
Removed useless pointer arithmetic from node operations
Removed stupid stripping of libmint.a (prevents linking :)
Modified mint_skip_space so that it also skip comments (# to end
of line)
Added normalize weight init operation to allow weights to be
normalized to a given value (weights are adjusted so that their
sum by row --- all weights feeding the same post-synaptic node
--- is given)
