Description
This is a generalization of #19887.
We would like to incorporate functions to find all solutions to some classes of linear equations in the Sunits of a number field. This builds on code by Christopher Rasmussen, Beth Malmskog, and Angelos Koutsianas, with contributions by Christelle Vincent, Alejandra Alvarado, and Mckenzie West. Based on work by Baker, Smart, de Weger, Yu, and others.

you need to build and check the doc. For instance, the correct syntax is
EXAMPLES:: sage: 2+2 4
with a double colon after EXAMPLES and an empty line just after.

1) This is not a correct syntax (around True):
+  ````True`` or ``False``
2) ..NOTE
, INPUT:
, OUTPUT:
and REFERENCES:
should also be followed by a blank line, so this is wrong, for example:
+ ..NOTE:: + The numerator should be as close to 1 as possible, especially as the rank of the `S`units grows large
Also the next lines should then be indented if and only if the block command ends with ::
3) + Example::
should rather be EXAMPLES::
4) COMMENT:
is not a standard block command, use nothing or ALGORITHM:
5) every single function must have a nonempty EXAMPLES::
block with useful doctests
6) comparison to None should not use prec == None
but rather prec is None
7) once again, you should build the doc, and look at it, until it is completely fine !
8) This is lacking ::
+ Use CRT to check the output + + sage: CRT(2, 2, 18, 27)
as well as here:
+ The order of the moduli matters. + + sage: len(compatible_vectors(a, 18, 12))
