Adding a program that fails because of wrap(). To be investigated.
Problem found: the function to be solved has an uncertainty: the result is not defined! The current version of uncertainties works better than that of http://jkitchin.github.io/blog/2013/03/07/Another-approach-to-error-propagation/, I think: it points to a problem instead of returning NotImplemented.
Merge branch 'fix_fsolve'
More emphasis on certain parts of the wrap() basic documentation.
