Detailed Description
Shape for class aff::Series.
aff::Series needs its own shape class to provide an Array compatible interface to Iterator.
The shape ist defined by three parameters, which are first, last, and base. The index k of the corresponding series must be in (first, last). While the range acessed within the representation is (first-base, last-base). Thus the element k of the series will be found at index k-base in the representation.
The shape guarantees that the memory layout is dense. This means that the elements of a series can be accessed like a C-style array through a pointer to the first element of the series.
Since we do not need to handle multiple dimensions, we offer in-class reshaping functions.
