NOTES: reverse: use the n-nary tree in commit2.c and only encapuslate data store. pass in func pointer for processing of commands below.

also, the algorithm for collapsing the tree into a transaction list is:
1) iterate through tree and mark all explicit transactions
2) when done, prune the tree of all root explicit transactions
3) Now iterate through remaining tree and remove each node and append to transaction list.
