Torch model for arrow of time prediction in the CVPR 18 paper

D. Wei, J. Lim, A. Zisserman, W. Freeman.
<b>"Learning and Using the Arrow of Time."</b>
in CVPR 2018.

## Demo:
1. training from scratch flow-TCAM model for AoT prediction  on UCF101
```
CUDA_ID=0,1,2;GPU_ID=1,2,3;CPU_N=10;
N_BATCH=32;N_FRAME=20;N_C=2
M_LABEL=2;M_LOSS=0;M_BEND=cudnn
M_DROPOUT=0.5,0.5;M_ARCH=vggbn_tcam_pair2
D_TYPE=2;D_PRE=5;D_NAME=flow%s_%04d.jpg;D_CROP=2;D_TCROP=1;
D_OUT=results/ucf_train/
D_TXT=data/@01_cnn_ta_flow_orig_fb.txt
E_SAVE=5;E_ALL=20;E_ST=1;E_SIZE=5000;E_ITER=3
E_PARAM=5.1

```

## Tips:
- to debug in lua, add this line:
`local dbg = require('util/debugger');dbg()`

- to visualize data in matlab, add this line:
`local matio = require 'matio'; matio.save('test.mat',{t1=data1,t2=data2})`
