Documentation bug in "Serialization Combinations" table

[ghost]

In the table available here: http://docs.pylonsproject.org/projects/colander/en/latest/null.html#serialization-combinations The first and last lines of the table are contradictory ("value serialized" versus "null serialized").

[tseaver]

I agree that there is a contradiction: my brain is too fuzzy at the moment to suggest the correction.

After using Colander, I think I can now say that it is the last line which is wrong.

Moreover, for clarification, it could be interresting to:

1. add the following combinaison: Value: < missing >, Default: < missing >
2. fuse the combinaisons having "value" in Value column in this: Value: value, Default: whatever, Result: value serialized
