Spaghetti Router Code

[JosephZhang-LDL]

There is an extreme inconsistency in our routers. In some of the navbars, half of the links are wrapper in while the other use the routeChange function. Half of the components use withRouter while the others don't. For the sake of consistency, someone needs to refactor all the code to use , apply withRouter everywhere where router is necessary, and avoid nesting tags within the main tag.
