* Get begin pointer of vector (non-const version).

* vector, as well as that of indexing after the end of the vector.
/**
* Important: Do not use the following functions in new code, but use v.data()
* and v.data() + v.size() respectively directly. They were once introduced to
* have a compatible, safe way to get the begin and end pointer of a vector.
* However with C++11 the language has built-in functionality for this and it's
* more readable to just use that.
