New description:
Continued fractions (in sage.rings.contfrac) do not do what we expect:
* it only deals with rational numbers
* there is no dedicated method for numerical approximations (which is one
of the first aim of continued fractions)
* there is no bridge with words (sage.combinat.words)
* there is no bridge with quadratic numbers (see also #11345)
Moreover, categories are not properly initialized nor used.
The patch proposed here improves the current version by addressing the
four issues above.
