Files & Folders Navigator

[arxdsilva]

To keep up with the project we need a func that READs and stores all Dir & Files. It might be a Map of Maps:

// Output:
map[
   "Dir": [
      "dir1": [
         "dir1Dirs": [
            "dir1DirsD": [],
            "dir1DirsFiles": [],
         ], 
         "dir1Files": [],
      ], 
      "dir2": [...], 
      "dir3": [...], 
      "dir4": [...], 
      ],
   Files: [
      "a",
      "b",
      "c",
   ],
]

• What we need is nested slices (or map) that gets It's folders and append them into the original folders;
  Example (pythonic):

slice_of_folders = [
[folderA, [folderAa, [more folders], folderAb, [...]]],
[folderB, [...]],
.
.
.
]

I think #32 is a better approach to this situation, so I'll close this and work on that issue.
