DMSwarmType - Defines the type of `DMSWARM`

Values:
+ `DMSWARM_BASIC` - defines N entries of varied data-types which the user may register.
- `DMSWARM_PIC` - suitable for particle-in-cell methods. Configured as `DMSWARM_PIC`, the swarm will be aware of, another `DM` which serves as the background mesh.
Fields specific to particle-in-cell methods are registered by default. These include spatial coordinates, a unique identifier, a cell index and an index for
the owning rank. The background mesh will (by default) define the spatial decomposition of the points defined in the swarm. `DMSWARM_PIC` provides support
for particle-in-cell operations such as defining initial point coordinates, communicating particles between sub-domains, projecting particle data fields on to the mesh.

DMSwarmPICLayoutType - Defines the method used to define particle coordinates within each cell. The layouts are constructured using the reference cell geometry

+ `DMSWARMPIC_LAYOUT_REGULAR` - defines points on a regular ijk mesh. In this case
the `fill_param` argument of `DMSwarmInsertPointsUsingCellDM()` defines the number of points in each spatial direction.
. `DMSWARMPIC_LAYOUT_GAUSS` - defines points using an npoint Gauss-Legendre tensor product quadrature rule. In this case
the `fill_param` argument of `DMSwarmInsertPointsUsingCellDM()` defines the number of quadrature points in each spatial direction.
- `DMSWARMPIC_LAYOUT_SUBDIVISION` - defines points on the centroid of a sub-divided reference cell. In this case
the `fill_param` argument of `DMSwarmInsertPointsUsingCellDM()` defines the number times the reference cell is sub-divided.
