I've added a couple of new functions to the Form class. There are now
various versions of set_coefficient() and set_coefficients().

One may set a coefficient based on its number of its name. One may
also set a whole bunch of coefficients at once (possibly a subset).

In particular, one may use a map from strings to coefficient pointers.

void set_coefficients(std::map<std::string, const Coefficient*> coefficients);

void set_coefficients(std::map<std::string, boost::shared_ptr<const Coefficient> > coefficients);

Then one may do

  my_coefficients["f"] = &f;
  my_coefficients["g"] = &g;

and then

  a.set_coefficients(my_coefficients);

Does this cover it?
