1.9.1 release with up-to-date documentation.
The master branch is for bleeding-edge public versions that are *not*
on PyPI (version on GitHub, instead).
More explicit documentation for UFloat.error_components().
Simpler, more realistic code.
Simpler text, code more explicit.
More appropriate section level: storing arrays in text format does not involve the unumpy module.
Fixed typo.
More consistent paragraph (loadtxt() did not apply strictly to storing arrays, but to reading them).
More explicit namespace.
