basic tree structures
- simple binary tree in GO
- Insert() func, inserts a node in appropriate location
- Randomint() func, return random int
- Search() func, find a node with given key
- invert_tree() func, inverts a binary tree
- print_in_order() func, prints node values in order
- Is_Tree_Symmetrical() func, checks symmetry of tree
- Are_Trees_Symmetrical() func, checks if two trees are symmetrical
- Valid_BST() func, verifies if a tree is a BST
- user interface
- more BT funcs
- custom data structure packages
- proper insert function that inserts node at the next empty space
- doc strings and notes for all funcs
- GO
