The purpose of this package is to factor out logic and
math common to Item Response Theory fitting, diagnostics, and
analysis. It is envisioned as core support code suitable for
more specialized IRT packages to build upon. Complete access to
optimized C functions are made available with
R_RegisterCCallable.
