TaoRegister

Adds a method to the TAO package for unconstrained minimization.

TaoRegister(char *name_solver,char *path,char *name_Create,int (*routine_Create)(Tao))

Not collective

	sname	- name of a new user-defined solver
	func	- routine to Create method context

TaoRegister() may be called multiple times to add several user-defined solvers.

   TaoRegister("my_solver",MySolverCreate);

Then, your solver can be chosen with the procedural interface via

    TaoSetType(tao,"my_solver")

or at runtime via the option

    -tao_type my_solver
