trac #2686 last details
trac #2686 adding the 120-cell graph

Trac 10963: attempt at improving the wording for quotients/subquotients
switch left<->right; expand explanations

- Renamed the shift_left_tranducer to shift_right_transducer, because
it actually was a right shift.
- Explained the right shift (as opposed to the left shift which
  would be reasonable at first sight)
- Changed DocTest for enforcing last digit zero in order to
  include a first digit zero to make it clearer what we actually check.
- Explain None in xor_transducer with earlier explanation.
- Enhance DocTest of xor_transducer to show what None does.
- Additional Doctest for xor_transducer
- explain construction of transducer in more detail, more links
- link to generators.GrayCode

Removed reference to HKW2014 from FiniteStateMachine.final_components

[HKW2014] is cited both in FiniteStateMachine.final_components and
in FiniteStateMachine.asymptotic_moments. Only one of them can be a
label, so the other one had to go. Not sure whether this is the
correct way, but so errors are avoided.
replaced one new instance of raise E, V by raise E(V) (cf. #15990)
explained the shifting in the Gray code-construction differently
Merge sage 6.2.beta8 together with the latest version of #10963 in #15801
a couple of minor changes during review

- ``X_n`` (and others) to Latex
- [...] to (...) for easier reading
- input_alphabet=... amended to make clear what is given
- PEP8 spacings
- added one short doctest to see output of transducer
- rewrote one try/catch-block so that only the line throswing exception is inside; rest outside
Trac 15801: added warning about not yet fully implemented subcategory tests
Merge branch 'u/chapoton/13291' of ssh://trac.sagemath.org:22/sage into 13291

FiniteStateMachine.asymptotic_moments: added two links in docstring

Examples 2 and 4 now link to the examples at the begin of the module.
FiniteStateMachine.asymptotic_moments: added explanation to third example
FiniteStateMachine.asymptotic_moments: add examples to examples

The examples section contained a few transducers where we now add examples
to show how these transducers act on their input. This also required setting
correct final states (those do not enter the asymptotic analysis anyway).
asymptotic_moments: add explanation on PolynomialRing vs SymbolicRing
asymptotic_moments: replaced parameter verbose by sage.misc.misc.verbose

However, in order to have the warning printed by default, it is at
level=0, so to silence it, set_verbose(-1) must be called, which is forbidden
by the documentation (but also seems to work).
