For use by apop_cdf when the CDF is generated via Monte Carlo methods.
For random draw methods, how many draws? Default: 10,000.
|gsl_matrix * apop_cdf_settings::draws_made|
A store of random draws used to calcuate the CDF. Need only be generated once, and so stored here.
|int * apop_cdf_settings::draws_refcount|
For internal use.
|gsl_rng * apop_cdf_settings::rng|
For random draw methods. See apop_rng_get_thread on the default.
