toFactorLoading

All slopes are divided by the ogive constant. Then the following
transformation is applied to the slope matrix,

Factor out logic
and math common to Item Factor Analysis 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().
