Comment:

 - The documentation does not build

 - Totally Rmified Fixed Point does not need initial caps.

 - "x**n + a*x**(n-2) +...+c" should not be "

 - the examples sage:: should only have one :.

 - the doc tests pass, but only because the examples with :: are not being
 run.

 - formatting of the code needs some attention, such as spaces around =

 - these two functions were added to the finite field section of polynomial
 morphism. Should they work over other rings/fields as well?

 - make_look_poly could use a better name. How about 'normal_form'? Since
 it has only one keyword, you should use the keyword instead of the dict
 kwds
