  TSRegisterDynamic - Adds a creation method to the TS package.

  Synopsis:
  PetscErrorCode TSRegisterDynamic(const char *name, const char *path, const char *func_name, PetscErrorCode (*create_func)(TS))

  Not Collective

  Input Parameters:
+ name        - The name of a new user-defined creation routine
. path        - The path (either absolute or relative) of the library containing this routine
. func_name   - The name of the creation routine
- create_func - The creation routine itself

  Notes:
  TSRegisterDynamic() may be called multiple times to add several user-defined tses.

  If dynamic libraries are used, then the fourth input argument (create_func) is ignored.

  Sample usage:
.vb
  TSRegisterDynamic("my_ts", "/home/username/my_lib/lib/libO/solaris/libmy.a", "MyTSCreate", MyTSCreate);
.ve

  Then, your ts type can be chosen with the procedural interface via
.vb
    TS ts;
    TSCreate(MPI_Comm, &ts);
    TSSetType(ts, "my_ts")
.ve
  or at runtime via the option
.vb
    -ts_type my_ts
.ve

  Notes: $PETSC_ARCH occuring in pathname will be replaced with appropriate values.
        If your function is not being put into a shared library then use TSRegister() instead
