Created LDBIter class and started fixing iters in iface
Mostly done updating iface and blockutils with new iters
New iterator code compiles...haven't run it yet
New iterator logic passes all old tests
Updated LDB block size and scanning is much faster!
Updated version before merging back into 0.91-dev
Fixed armoryd.py listtransactions and getledger
Merge branch '0.91-dev' of github.com:etotheipi/BitcoinArmory into 0.91-dev
Testing out save-scraddr-hist-every-block...seems good so far
