//   # The multiarray declares a generic multi-dimensional array of a
//   # particular data type.  Dimensions are ordered from outer most
//   # to inner most.
//   
//   MultiArrayDimension[] dim # Array of dimension properties
//   uint32 data_offset        # padding elements at front of data
//   
//   # Accessors should ALWAYS be written in terms of dimension stride
//   # and specified outer-most dimension first.
//   # 
//   # multiarray(i,j,k) = data[data_offset + dim_stride[1]*i + dim_stride[2]*j + k]
//   #
//   # A standard, 3-channel 640x480 image with interleaved color channels
//   # would be specified as:
//   #
//   # dim[0].label  = "height"
//   # dim[0].size   = 480
//   # dim[0].stride = 3*640*480 = 921600  (note dim[0] stride is just size of image)
//   # dim[1].label  = "width"
//   # dim[1].size   = 640
//   # dim[1].stride = 3*640 = 1920
//   # dim[2].label  = "channel"
//   # dim[2].size   = 3
//   # dim[2].stride = 3
//   #
//   # multiarray(i,j,k) refers to the ith row, jth column, and kth channel.
// Instances of this class can be read and written with YARP ports,
// using a ROS-compatible format.
