Fix an issue with fSumw2 not being told how many bins there are when going via default c'tor, as in the case of CreateHn.
Zero-initialize fCoordBuf to make Dump() valgrind-happy: accesses uninitialized memory otherwise to print the value that fCoordBuf points at.

Implement THn::CreateHn() and THnSparse::CreateSparse() taking a THnBase (which in turn call THnBase::CreateHnAny() taking a THnBase):
converts a THn to a THnSparse and vice versa, keeping the bin type.
Can also be used to clone a THnBase-derived object.
Move storage initialization into separate (pure virtual) function
such that the common initialization part can end up in a new function THnBase::Init() which is called by (the now non-virtual) CloneEmpty() and CreateHnAny().

Add non-sparse, n-dimensional histogram THnD, THnF, THnI...
THn and THnSparse now both derive from THnBase, providing the common interfaces and algorithms.
Extend stress suite to cover THn, too.
THn uses TNDArray for bin storage, an n-dimensional array. It provides an interface to extract an element by a series of operator[]:
Double_t value = arr[0][2][1][5];
