Tree Implementation (Weiss Ch18)
1. MyFileSystem.java to illuatrate how tree is used to display files in file system); output looks like this (same code as FileSystem.java from Weiss).
2a. MyBinaryTree.java uses MyBinaryNode.java, a simplified version to explain tree construction and inorder traversal only, output looks like this
2b. BinaryTree.java uses BinaryNode.java (very useful tree implementation) from Weiss
