The new operators are now in place:

    dot  - scalar product
    grad - gradient
    div  - divergence
    rot  - rotation (curl works also)

One can now write things like

    a = div(grad(dot(rot(v), u)))*dx

Please try them out and tell me if they work. Suggestions for
modifications of the behavior of these operators as well as
suggestions for new (standard) operators that might make life easier
for you are also welcome. Remember, these operators are defined
independently from and on top of the form algebra so adding a new
operator does not add to the complexity of the form language (this
comment is for you Rob ;-).
