Documenting axes tick options

[aris-mav]

As discussed in this discourse post, the documentation for the axes tick options would probably be better if some examples are added.

e.g, with:

• LinearTicks, an alternative tick finder for linear ticks
• LogTicks, a wrapper that applies any other wrapped tick finder on log-transformed values

, it is not obvious how to use these methods.
Help mode in the repl does not provide much info either.
