/*
STEPS::
1. Create a function to IGNORE ALL links. (basically to click on all ignore button)
	a. get all ignore button using XPATH
	b. iterate through them clicking everyone (with few exception)
2. Add IGNORE ALL button to frontend i.e. facebook which will fire above function (Give user absolute control)
	a.
