delay swap_plan() by 3 more iterations

update train

correct swap_sched(), swap_select(),swap_plan()

correct load update in swap_select

vec_run changed to new 3 iterations

correct vec_run36 index issue

correct overhead issue, verify vec_run.t

vec_run duplicate to avoid sorting issue

verified itm 5 indices in Table_sched

vec_swap_select pass by reference in swap_sched()

impl swap_update_tables(), before DeploySwap(), both at Append()

for time being, remove negative r_idx itms && git push origin vd1

handle last itr by impl sizeSqn and verification to change asyncSwapFlag back to 0

correct swap_construct_tables(), included negative r_idx for swap_update_tables() and DeploySwap()

include negative r_idx for DeploySwap()

impl GetRealGpuPtr() to swapIn nullptr Block at last iteration

impl GetRealGpuPtr(), and optimize data() and mutable_data()

impl GetRealGpuPtr(), and optimize data() and mutable_data()

verify const issue

change to return tempData instead of updating data_

without remove erasing in Table_not_at_device

milestone of last itr, at 550 MB

new class of pool: SwapPool
important APIs: PoolOpt(), Malloc(), Free()
PoolOpt() takes in M/F sequences including those induced by swapping
cross-iteration variables and last iteration case solved.

record down MF after swap done, for one iteration
