AtomMag 1.0-beta

This is a pre-release version of AtomMag, a GPU-accelerated Atomistic Spin Dynamics software package that can be used to simulate evolution of atomic spin moment. It includes following features:
1.Various Lattice type provided including simple cubic, face-centered cubic and 2D hexagonal lattice. Self-defined atomic position can also be input through 'atomposition.in'
2.Heisenberg exchange interaction, Dzyaloshinskii–Moriya interaction, uniaxial magnetocrystalline energy, dipole-dipole interaction and zeeman energy are considered
3.Spin orbit torque can be simulated
4.Fortran code paralleled using OpenACC
