      Parses the GPS program output (using taskMetadata, which should be verified by the caller),
      and registers the facts of the tasks which were executed.

      The first entry in taskMetadata is the number of tasks.

      For each task, the structure is as follows:
        1. Size (including the size and hash fields).
        2. Program hash.
        3. The number of pairs in the Merkle tree structure (see below).
        4. The Merkle tree structure (see below).

      The fact of each task is stored as a (non-binary) Merkle tree.
      Leaf nodes are labeled with the hash of their data.
      Each non-leaf node is labeled as 1 + the hash of (node0, end0, node1, end1, ...)
      where node* is a label of a child children and end* is the total number of data words up to
      and including that node and its children (including the previous sibling nodes).
      We add 1 to the result of the hash to prevent an attacker from using a preimage of a leaf node
      as a preimage of a non-leaf hash and vice versa.

      The structure of the tree is passed as a list of pairs (n_pages, n_nodes), and the tree is
      constructed using a stack of nodes (initialized to an empty stack) by repeating for each pair:
      1. Add n_pages to the stack of nodes.
      2. Pop the top n_nodes, construct a parent node for them, and push it back to the stack.
      After applying the steps above, the stack much contain exactly one node, which will
      constitute the root of the Merkle tree.
      For example, [(2, 2)] will create a Merkle tree with a root and two direct children, while
      [(3, 2), (0, 2)] will create a Merkle tree with a root whose left child is a leaf and
      right child has two leaf children.

  isValid() function of the registry with a given hash.

  In addition, each fact registry exposes a registry specific function for submitting new claims
  together with their proofs. The information submitted varies from one registry to the other
