Allow args and kwds to take constant values #10

It would be nice to be able to populate parameters with fixed values, rather than having to source them from a node. So, for example, the code below would call f with x as the value taken from input_node, but with y always set as "FOO":

def f(x,y):
   ...
comp.add_node('a_node', f, args=['input_node', C("FOO")])
