Add use of MatrixAlgebraKit.default_algorithm to decomposition documentation #167
Description
In order to customize decompositions using keyword arguments rather than passing explicit algorithm instances, e.g.
f(A; kwargs...) -> F...currently, it's a bit tricky to figure out which keyword arguments are available, since these are very algorithm-dependent. While this algorithm-dependence is emphasized in the documentation and all the algorithm docstrings nicely document their kwargs, it is not actually that obvious how a user can figure out which algorithm is used for which decomposition by default.
To address this, it would be nice to explicitly mention the use of MatrixAlgebraKit.default_algorithm as a quick way to figure out what algorithm is used by default, and by extension what keyword arguments a user can pass to a decomposition.
I'm happy to file a PR containing a few lines that try to explain this. One potential problem with this is that default_algorithm is not currently exported, so explicitly advertising its use might look a bit weird. Would there be any issues with exporting default_algorithm?
