126   TSRegisterDynamic - Adds a creation method to the TS package.
127 
128   Synopsis:
129   PetscErrorCode TSRegisterDynamic(char *name, char *path, char *func_name, PetscErrorCode (*create_func)(TS))
130 
131   Not Collective
132 
133   Input Parameters:
134 + name        - The name of a new user-defined creation routine
135 . path        - The path (either absolute or relative) of the library containing this routine
136 . func_name   - The name of the creation routine
137 - create_func - The creation routine itself
138 
139   Notes:
140   TSRegisterDynamic() may be called multiple times to add several user-defined tses.
141 
142   If dynamic libraries are used, then the fourth input argument (create_func) is ignored.
143 
144   Sample usage:
145 .vb
146   TSRegisterDynamic("my_ts", "/home/username/my_lib/lib/libO/solaris/libmy.a", "MyTSCreate", MyTSCreate);
147 .ve
148 
149   Then, your ts type can be chosen with the procedural interface via
150 .vb
151     TS ts;
152     TSCreate(MPI_Comm, &ts);
153     TSSetType(ts, "my_ts")
154 .ve
155   or at runtime via the option
156 .vb
157     -ts_type my_ts
158 .ve
159 
160   Notes: $PETSC_ARCH occuring in pathname will be replaced with appropriate values.
161         If your function is not being put into a shared library then use TSRegister() instead
