@lxmota just an FYI, I noticed you were doing some inplace scattering in a commit in Carina and wanted to point you to some of the existing methods in FEC.

If you look here there's several methods with scatter_ in the name. They inplace update the residual/stiffness storage so we don't need to form large static arrays. I've noticed some nice reductions in initial start up times for problems by using these instead of the methods that form the full discrete gradient.

They're not perfect yet but a good start.

Solid mechanics examples can be found in Cthonios here. For reasons that escape me now I changed the ordering of the inputs.

To opt in, there's a keyword argument in SparseMatrixAsembler called use_inplace_methods which should be set to true.

This PR adds some more of these scatter methods.
