+// use tree for leafs in the node

+// don't store size in the tree
+// better use RB tree
+
+// each node type has different size
+// implement node using virtual functions and inheritance
+// only directory node has leafs (tree)
+
+// make two classes - emulator and interpreter
+// emulator stores only lower case names
+
+// store number of incoming hard links in the node cache to ensure no hard-linked nodes can be removed
+
+
+// convert command to lowercase then use full path as the key and update key pointer when descending to the leafs
+
+// each node has parent pointer to check for current directory
+
+// base node class has all the cache data. use it directly in the tree
