Hi Miguel,

Here's an example below. The multiarray itself I am sending is not
valid as I made up fake dimensions.

$ rosmsg show Float64MultiArray
[std_msgs/Float64MultiArray]:
std_msgs/MultiArrayLayout layout
  std_msgs/MultiArrayDimension[] dim
    string label
    uint32 size
    uint32 stride
  uint32 data_offset
float64[] data

ninja:~ kwc$ rostopic pub f64 std_msgs/Float64MultiArray """
layout:
  dim: [{label: 'x', size: 1234, stride: 1},{label: 'y', size: 1234,
stride: 1} ]
  data_offset: 0
data: [1.0, 2.0, 3.0, 4.0]
