Added the Netket operator computing the Rényi2 entanglement entropy in netket_fidelity/renyi2 with corresponding test.
Added the scripts for the simulation of a quantum trajectory consisiting of alternated layers of unitary dynamics (generated by the 2D TFIM Hamiltonian) and projective measurements in the z basis in netket_fidelity/examples/dynamics_with_measurements. The folder contains also the files defining the initial states of the simulation at t=0 for two system sizes.
Added a raising error when the operator that are used in the driver have a non-Spin Hilbert space.
Updated README fileswith more details on the installation of the package.
