Description of purpose/function:

In order to efficiently navigate and iterate over the 5d bins in FPGATrackSimGenScanTool, a dedicated array class has been developed. Multidimensional arrays in stl don't appear until c++23 at the earliest and have not been evaluated for appropriateness.
This array can have an arbitrary number of dimensions set by an std:vector (dims) with the size of the number of demensions and the size in each dimension set in the constructor or later by the "setsize" method.
The implemenatation uses an std::vector to avoid an direct memory management. The requried size is calcuated from the m_dims vector.
For accessing elements, it converts a index std::vector<unsigned> of length Ndim (idx) into a single int index into the 1d std::vector.
It has a standard iterator so you can iterate with "for (auto &bin : myArray)" where bin would be an iterator with two accessors bin.idx() gives the size N-dim std:vector<unsigned> which is N-dim index the iterator is on and bin.data() which is a reference to the content of the array for that index
