print.internal_boot

Conduct internal validation of a clinical prediction model for a binary outcome.
Produce bias corrected performance metrics (c-statistic, Brier score, calibration intercept/slope)
via bootstrap (simple bootstrap, bootstrap optimism, .632 optimism) and cross-validation (CV optimism,
CV average). Also includes functions to assess model stability via bootstrap resampling.
