errors in test-ocr

[yunkaili]

below is the running log. i added some printf in the program.
and locate the error happens at line 60 in the file clstm_compute.h
the code calls the sum function of a tensor1 variable.

the version of Eigen i use is Eigen3.3-beta1

need some help here, thank you

update:
problem solved.
it is probably caused by the function in the tensor module in Eigen.
two function calls assertion.
one at line 60 of the file ctc.cc, sum(out) which sums all the element in out
the other at line 79 of the same file, maximum(both) which returns the maximum value of all elements in both.
re-implement this two function by yourself and the test will work

Try again; I finally merged the Eigen::Tensor version into the master branch. There are a several built-in test cases now.
