Outstanding; it works beautifully!

Dear Torquil,

You are right, a function equivalent to "add_fem_name" do not exist for
integration methods. Of course, since the two systems for fems and
integration method derive from the same mechanism (dal_naming_system),
the same function can be easily added to It
should be as follow:

void add_integration_name(std::string name,
             dal::naming_system<integration_method>::pfunction f) {
     dal::singleton<im_naming_system>::instance().add_suffix(name, f);

I add it to the svn version of getfem.

I have created a custom mesh_fem, and I made it available in my
program using the code

getfem::add_fem_name("CUSTOM", custom_fem);

where custom_fem is a function that returns a getfem::pfem, similarly
to how it is done for the built-in mesh_fems in the Getfem source code.

I select this mesh_fem using the syntax


However, now I would like to create my own integration method
IM_CUSTOM to go with FEM_CUSTOM. My goal is to define an integration
method that is exact on FEM_CUSTOM.

Is there a nice way to do this without recompiling the Getfem source
code? I didn't find any functions analogous to "add_fem_name", but for
integration methods rather than mesh_fems.
