the `expr` is evaluated silently in the kernel (without) output in

Parameters
----------
expr : string
valid string to be executed by the kernel.
callback : function
function accepting one arguement, as a string. The string will be
the `repr` of the result of evaluating `expr`
The `callback` is called with the 'repr()' of the result of `expr` as
first argument. To get the object, do 'eval()' onthe passed value.
