Create ILSpyTreeNodes for entire assembly

[unkown512]

Given an assembly file, how is ILSpy creating the treeNodes that is used when navigating the gui?

Each method is pulled out and then these nodes are used to create an IMethod that can be used to help initialize an ILReader()

My goal is to just get the ILAst for the entire file without having to click each gui node in the tree viewer
