The Material Point Method in 1D

[@abhishekganguly7695]

Initially, at t=0, are all the velocities given at material points and THEN interpolated at nodes?

In this example, I initialized the nodes and then interpolated to the particles.
However, you should be able to initialize the particles then interpolate to the nodes without any consequences.
