State of the field in JOSS paper

[mscroggs]

There is not very much discussion of how AsFem compares to other finite element libraries in the JOSS paper. Libraries that you could mention include:

• FEniCS: website, GitHub repos, paper
• MFEM: website, GitHub repo, paper
• deal.ii: website, GitHub repo, paper
• DUNE: website, GitHub repos, paper
• FreeFEM: website, GitHub repos

I'd like to second this comment as a reviewer. There are a lot of very successful and tested, general-purpose FEM libraries out there. I fail to see a proper motivation in the JOSS paper on why there was a need to create a new one, instead of using the capabilities in the ones that @mscroggs has listed above. I'd probably also add libMesh and MoFEM to that list as well given the wide variety of applications where they have been used.

Dear @mscroggs and @vijaysm , thanks for the comments, I have added the statement for the comparsion.

The manuscript reads much better now in the statement of need section.
