/**\brief This class defines a board with several markers.
* A Board contains several markers so that they are more robustly detected.
*
* In general, a board is a set of markers. So BoardConfiguration is only a list
* of the id of the markers along with the position of their corners.
*
* The position of the corners can be specified either in pixels (in a non-specific size) or in meters.
* The first is the typical case in which you generate the image of board and the print it. Since you do not know in advance the real
* size of the markers, their corners are specified in pixels, and then, the translation to meters can be made once you know the real size.
*
* On the other hand, you may want to have the information of your boards in meters. The BoardConfiguration allows you to do so.
*
* The point is in the mInfoType variable. It can be either PIX or METERS according to your needs.
*
