Changes to predictors now result in checking validity and updating current fits.
Various cleaning actions done to setPredictor/testPredictor interface.
Initial, broken import.
Library bug fix.
Merge branch 'master' into binaryIO
binary IO now complete in C++, requires R interface for loading
rng isolation and reimplementation
Fixes for old Knuth rng; hooked R interface to use R runif.
Normals now feed correctly from R's RNG for types < user. tests now pass too.
Merged with predictorReset
Now supports R's built-in normal generator; uses own implementation only if C/C++ constructed to do so.
external brought into parity with cibart
Windows/linux compatibility and some uninitialized/orphaned memory
