How to use this ROS wrapper?

[zjudmd1015]

Hi author,

Can you please make it more clear about how to use this ROS wrapper? I keep running into a problem about Eigen library, but I suppose it is because I wrongly used this wrapper.

Thanks!

The error info goes like this:
*
/usr/include/eigen3/Eigen/src/Core/DenseStorage.h:128: Eigen::internal::plain_array<T, Size, MatrixOrArrayOptions, 32>::plain_array() [with T = double; int Size = 16; int MatrixOrArrayOptions = 0]: Assertion `(reinterpret_cast<size_t>(eigen_unaligned_array_assert_workaround_gcc47(array)) & (31)) == 0 && "this assertion is explained here: " "http://eigen.tuxfamily.org/dox-devel/group__TopicUnalignedArrayAssert.html" " **** READ THIS WEB PAGE !!! ****"' failed.
