PanoramaInit
============

**Description**

This node allows to setup the Panorama:
1/ Enables the initialization the cameras from known position in an XML file (provided by a motorized panorama head).
2/ Enables to setup Full Fisheye Optics (to use an Equirectangular camera model).
3/ To automatically detects the Fisheye Circle (radius + center) in input images or manually adjust it.
