-- A PMConfig structure has a bunch of configuration values used by
-- many functions in PMInstanceGenerator, ProposalMatcher, and Evaluation, which
-- take a PMConfig as their first argument.  Module PMDefaults defines a sane
-- default configuration `pmDefaults'; it can be used as-is or individual fields
-- can be overridden, e.g., pmDefaults{loadTolerance = 2} .  See module
-- PMDefaults for documentation of each field.
