update to initialization and main script

added variation in hidden size between AEs
updated output of plot to show error and hidden size
going to try moving size out of config
lots of changes

redid the plot, a lot more information now
mutation is working
fixed a BIG but in that the size of the AE was being stored in a common
file across all AEs. only affected output but made it really hard to
determine anything
updated selection method. much more selective now, based on range
instead of sum. may change it back at a later date to test the
difference.
