Mark OLESEN authored- the previous code used a dual-purposed graphRow for non-const/const access. However, clang 4.0 rightly identifies there being no constructor path from "graphRow<T>" to a "graphRow<const T>". Since the row-access is a somewhat similar concept to an STL-iterator, now provide non-const and const versions of the row access.
