added functionality to evulate symbolic ACADO functions at templated evaluation points. (for an example see /examples/basic_data_structures/templated_function_call.cpp)

added symbolic generation of the Taylor coefficients of the solution of an ODE. The routine works for any expansion order (see examples/basic_data_structures/ode_taylor_expansion.cpp)
