#------------- Main script ---------------
# This script sets various options on a ocUtils object, and then runs the desired action.
# ocUtils is a convenience wrapper around the basic occam3 objects, and it sets appropriate
# defaults if you don't set every option.

# For settings which require model attribute names, the allowed values include:
# h, t, df, ddf, loops [1=loops, 0=no loops]
# information, unexplained, ipf_iterations, lr, alpha, beta, level, aic, bic
# cond_h, cond_dh, cond_pct_dh, cond_df, cond_ddf, p2, p2_alpha, p2_beta
# (Note that the Pearson statistics aren't computed by default because they are expensive.)
# To force a particular attribute to be printed as an integer, append "$I" to the name (e.g., Level$I)
