I think it might be handy to pass the threshold to this method explicitly and set it to 0.5 by default, so clients can customise the behaviour if needed

Should we address match_threshold?

This represents my vision for how clients should expose the template matching functionality with opencv. I.e., return a "clone" of WebElement with a smaller set of methods, so users can imagine they are simply finding "elements" and clicking on them.
Note that tests will only pass with appium/appium-support#74 applied to the Appium server used for testing.
