+This test is meant to exercise activation of the first version bits soft fork
+This soft fork will activate the following BIPS:
+BIP 68  - nSequence relative lock times
+BIP 112 - CHECKSEQUENCEVERIFY
+BIP 113 - MedianTimePast semantics for nLockTime
+
+regtest lock-in with 108/144 block signalling
+activation after a further 144 blocks
+
+mine 82 blocks whose coinbases will be used to generate inputs for our tests
+mine 61 blocks to transition from DEFINED to STARTED
+mine 144 blocks only 100 of which are signaling readiness in order to fail to change state this period
+mine 144 blocks with 108 signaling and verify STARTED->LOCKED_IN
+mine 140 blocks and seed block chain with the 82 inputs will use for our tests at height 572
+mine 3 blocks and verify still at LOCKED_IN and test that enforcement has not triggered
+mine 1 block and test that enforcement has triggered (which triggers ACTIVE)
+Test BIP 113 is enforced
+Mine 4 blocks so next height is 580 and test BIP 68 is enforced for time and height
+Mine 1 block so next height is 581 and test BIP 68 now passes time but not height
+Mine 1 block so next height is 582 and test BIP 68 now passes time and height
+Test that BIP 112 is enforced
+
+Various transactions will be used to test that the BIPs rules are not enforced before the soft fork activates
+And that after the soft fork activates transactions pass and fail as they should according to the rules.
+For each BIP, transactions of versions 1 and 2 will be tested.
+----------------

+bip113tx - modify the nLocktime variable
+
+BIP 68:
+bip68txs - 16 txs with nSequence relative locktime of 10 with various bits set as per the relative_locktimes below

+bip112txs_vary_nSequence_9 - 16 txs with nSequence relative_locktimes of 9 evaluated against 10 OP_CSV OP_DROP
