    Add code to compute in-order mappings for tokens. · cfb02ddc

    Add av1_indices_from_tree() function that computes a forward and inverse
     mapping of the tree leaf-node symbols to their in-order traversal.
    This is necessary because many of the aom_tree binary trees have their
     leaf nodes out of order (e.g., an in-order traversal of a tree with n
     nodes does not start at symbol 0 and go to symbol n - 1), but the CDFs
     created by tree_to_cdf() are indexed in-order.
