/**
* Label meta data in OpenIGTLinik protocol
*
* LBMETA is a data type to send a list of label image data available in a server.
* In OpenIGTLink protocol, actual label data is transfered as an IMAGE message.
* LBMETA message lets the receiving client know which IMAGE data are available
* as label maps.
* Multiple labels in a LBMETA message can point the same IMAGE message, if there
* are multiple lables are recoreded in a single IMAGE mesage. For example, given
* the following label map as IMAGE data with name "LableImage1":
*
* 0 0 0 1 0 0 value | name / description
* 2 0 1 1 1 0 --------+----------------------------
* 2 2 1 1 1 0 0 | None
* 2 2 2 1 0 0 1 | Liver
* 2 2 2 2 0 0 2 | Kidney
*
* To send the label information recorded in "LabelImage1," one can create
* a following LBMETA message:
*
* DATA | Contents
* ---------------+---------------------------
* NAME 1 | Liver
* IMAGE NAME 1 | LabelImage
* Labe l | 1
* RGBA 1 | 0xFF0000
* SIZE 1 | (6, 5, 1)
* OWNER 1 |
* --------------+---------------------------
* NAME 2 | Kidney
* IMAGE NAME 2 | LabelImage
* Labe 2 | 2
* RGBA 2 | 0xFF2222
* SIZE 2 | (6, 5, 1)
* OWNER 2 |
* --------------+---------------------------
*
* ... ....
*
* --------------+---------------------------
*
* The client determins the number of image meta by the size of the body included
* in the message header (see igtl_lbmeta_getdata_n() macro).
