- OSspecific: chmod() -> chMod(), even although it's not used anywhere - ListOps get subset() and inplaceSubset() templated on BoolListType - added UList<bool>::operator[](..) const specialization. Returns false (actually pTraits<bool>::zero) for out-of-range elements. This lets us use List<bool> with lazy evaluation and no noticeable change in performance. - use rcIndex() and fcIndex() wherever possible. Could check if branching or modulus is faster for fcIndex(). - UList and FixedList get 'const T* cdata() const' and 'T* data()' members. Similar to the STL front() and std::string::data() methods, they return a pointer to the first element without needing to write '&myList[0]', recast begin() or violate const-ness.
