@lebuller I will write this up once the rest of the document is mostly finished

- A robust and modular collection of PIC algorithms which are scalable and performance portable
- What open source, portable packages exist? VPIC 2.0, PUMI-PIC, IPPL
- Which ones are independent of application area (plasma, solid/fluid mechanics (MPM), astro)?
- Which ones include implementations of the most cutting-edge algorithms (APIC, PolyPIC)? Not sure if the university codes are available

@kwitaechong is writing the example on the dam break problem and merging to repo. I will help him writeup when complete

Future work section is optional, but a mention of the new PIC scheme refs and how algorithmic development fits in here and/or app development would be good somewhere
- Added parallel Hopf-Lax reference

| `Picasso` provides an interface for various supported linear algebra types defined in `FieldTypes`: `Scalar`, `Vector`, `Matrix`, as well as specialized support for higher-rank `Tensor3`, `Tensor4`, and `Quaternion` types. Field tags need only derive from these types in order to make use of `Picasso` linear algebra features. Although all basic operations on vectors and matrices are implemented, several specialized operations are also available, including matrix determinant, inverse, exponential, LU, and SVD decompositions, higher-order tensor contractions, and quaternion-matrix conjugation. | ||

Need to make sure to include what order each scheme goes up to
