1089661 - Add more in-depth documentation on the various strategies of marionette.find_element()

Status: NEW

Description

[Andrew Halberstadt [:ahal]]

There are a bunch of search strategies you can use with the find_element() and find_elements() api. They all work slightly differently, they have different expected "target" values, some don't work in chrome, and in bug 1080764 I'm adding two strategies that only work with anonymous nodes (one of which doesn't work with find_elements).

While they are all mentioned in passing from the find_element api docs, I think having a dedicated paragraph including examples for each strategy would be very helpful.
