MRtrix3 provides a set of tools to perform various advanced diffusion MRI analyses, including constrained spherical deconvolution (CSD), probabilistic tractography, track-density imaging, and apparent fibre density
PerThread and Shared classes in threaded_loop.h now longer use references as data members, but instead they use pointers. This fixes some errors when compiling with C++20 as the minimum standard (due to errors in initialising the variables in the constructors) and also allows us to avoid following the rule of 5 (e.g. no need to define custom copy/move constructors and assignment operators).
More generally, I think we should try to avoid using references as data members of classes because they limit the implementation of a class and also slightly hurt readability (for example, it's not obvious when accessing the member that it is a reference).
