Selenium.AssertElementImage is missing in the documentation

[Keonik1]

Could you update the documentation, because I understand that several functions have been added, including AssertElementImage, which is missing from the documentation?

Or if there are difficulties with updating the documentation, could you write in this issue a list of key properties that have been added but not documented? Preferably with their short description.

For example:
Selenium.AssertElementImage - Compare current page with expected screenshot
