Consolidated target lists for aliases.
SConstruct now builds a useful directory structure allowing more shared state.  Once the data_directory is populated with the data and script links, they can be reused.  Moreover, for each seed used in a build, a new directory is created to hold all of the initial training sets and derived models, so they need only be created once per seed.
The proportion of the data to go to the training set is now a parameter, set by default to .99.
Score Integrator takes a directory populated with subdirectories of the form 'seed_x' and integrates the scores for each parameter set over all of the seeds.
SConstruct now reports integrated scores, albeit in an ugly format.

Variation proposer now takes the error probability and computes the error term for each variation.
Corrector now uses the new variation proposer information to compute error probability.
