This is a templated, self-contained, single header implementation C++ class for parsing array slice operator strings that specify a min, max, and stride, such as "1:10:2", "::3" or "-1,-5,-2". There is an option to use any offset based indexing desired, such as 0-based for C/Python arrays, or 1-based for Fortran/MATLAB indexing. Reverse indexing is allowed, as well as relative to an array end. This class won't do the actual slice/sampling of an array; instead it only parses a string and returns the index limits and stride, or an STL vector of indices if desired.
