Julia modules for exact diagonalization of 1D Heisenberg model

$H = \sum_i(J^x S_i^x S_{i+1}^x + J^y S_i^y S_{i+1}^y + J^zS_i^z S_{i+1}^z) + \sum_i h_i^{\phantom{*}} S_i^\mathrm{ax}$

and exact time-evolution

$\mathbf{v}(t) = U^\dagger \mathrm{e}^{-iD t} U \mathbf{v}_0,$ where $H = UDU^\dagger$ .
