Adds a new `PetscFEType` 
## Synopsis
```
#include "petscfe.h" 
PetscErrorCode PetscFERegister(const char sname[], PetscErrorCode (*function)(PetscFE))
```
Not Collective


## Input Parameters

- ***sname -*** The name of a new user-defined creation routine
- ***function -*** The creation routine



## Sample usage
```none
    PetscFERegister("my_fe", MyPetscFECreate);
```


Then, your PetscFE type can be chosen with the procedural interface via
```none
    PetscFECreate(MPI_Comm, PetscFE *);
    PetscFESetType(PetscFE, "my_fe");
```

or at runtime via the option
```none
    -petscfe_type my_fe
```





## Note
`PetscFERegister()` may be called multiple times to add several user-defined `PetscFE`s
