DRY run of how to calculate the transaction ancestory

T1 from [a1] to [a3, a4] TMP_HASH = {a3 => [T1], a4 => [T1]}

T2 from [a4] to [a5, a6, a7] TMP_HASH = {a3 => [T1], a4 => [T1], a5 => [T2], a6 => [T2], a7 =>[T2]}

T3 from [a5] to [a1] TMP_HASH = {a3 => [T1], a4 => [T1], a5 => [T2], a6 => [T2], a7 =>[T2], a1 => [T3]}

T4 from [a1] to [a10, a11, a12] TMP_HASH = {a3 => [T1], a4 => [T1], a5 => [T2], a6 => [T2], a7 =>[T2], a1 => [T3]}
