Review comment:
It is almost okay: there are two failed unit tests SoftPlusCpp, and
SoftPlusCuda:
```
[ RUN ] TensorMath.SoftPlusCpp
/home/ubuntu/incubator-singa/test/singa/test_tensor_math.cc:132: Failure
Value of: dptr1[0]
Actual: 0.693147
Expected: log(2.0f)
Which is: 0.693147
/home/ubuntu/incubator-singa/test/singa/test_tensor_math.cc:133: Failure
Value of: dptr1[1]
Actual: 1.31326
Expected: log(exp(1) + 1.0f)
Which is: 1.31326
[ FAILED ] TensorMath.SoftPlusCpp (0 ms)

[ RUN ] TensorMath.SoftPlusCuda
/home/ubuntu/incubator-singa/test/singa/test_tensor_math.cc:1243: Failure
Value of: log(2.0f)
Actual: 0.693147
Expected: dptr[0]
Which is: 0.693147
/home/ubuntu/incubator-singa/test/singa/test_tensor_math.cc:1244: Failure
Value of: log(exp(1) + 1.0f)
Actual: 1.31326
Expected: dptr[1]

[ FAILED ] TensorMath.SoftPlusCuda (5 ms)

[ FAILED ] 2 tests, listed below:
[ FAILED ] TensorMath.SoftPlusCpp
[ FAILED ] TensorMath.SoftPlusCuda
```
This can be simply solved by changing the line EXPECT_EQ to EXPECT_NEAR with
the error limit of 1e-5.
Four lines are needed to change: line 132,133, 1243, 1244
Then the test will be passed and my review is done :)
