LFortran and Computational Chemistry

The overarching goal of the project is to have a minimum viable project which can compile the dftatom project which is of personal interest to me as a computational chemist. Following through with the initial contributions I made fulfilling the patch requirement, I shall work towards the completion of the math library. In particular, I intend to complete the tasks for the new Fortran runtime library. To be pragmatic and get an MVP, I shall work on allowing LFortran to use externally compiled modules. Subsequently, I shall work on the implementation of arrays and their intrinsics and round out the project by enumerating all remaining corner-cases required for the dftatom project.
