Detailed description
__________________________________________________________________

 * |OVP_DocBegin_BoxAlgorithm_KappaCoef_Description|
 * This box computes the Cohen kappa coefficient that allows to compare the accordance of two classifiers (https://en.wikipedia.org/wiki/Cohen%27s_kappa),
 * The box compares the results of the classifier (second input) to the 100% match classifier (first input).
 * 
 * The result is streamed on the first output, and is displayed in real time in a standalone visualization.

 * |OVP_DocBegin_BoxAlgorithm_KappaCoef_Inputs|
 * |OVP_DocEnd_BoxAlgorithm_KappaCoef_Inputs|

 * |OVP_DocBegin_BoxAlgorithm_KappaCoef_Input1|
 * The first input receives the expected stimulation.
 * |OVP_DocEnd_BoxAlgorithm_KappaCoef_Input1|

 * |OVP_DocBegin_BoxAlgorithm_KappaCoef_Input2|
 * This input receives the stimualtions found by the classifier.

Settings description
__________________________________________________________________

 * |OVP_DocBegin_BoxAlgorithm_KappaCoef_Settings|
 * Each setting except the first one corresponds to the stimulation code of a class. A stimulation must be unique. 
 * |OVP_DocEnd_BoxAlgorithm_KappaCoef_Settings|

 * |OVP_DocBegin_BoxAlgorithm_KappaCoef_Setting1|
 * This setting indicates the amount of classes handled by the box. This setting will change the amount of setting.
 * |OVP_DocEnd_BoxAlgorithm_KappaCoef_Setting1|

 * |OVP_DocBegin_BoxAlgorithm_KappaCoef_Setting2|
 * This setting indicates the stimulation corresponding to the first class.
 * |OVP_DocEnd_BoxAlgorithm_KappaCoef_Setting2|
 * 
 *  * |OVP_DocBegin_BoxAlgorithm_KappaCoef_Setting3|
 * This setting indicates the stimulation corresponding to the second class.
 * |OVP_DocEnd_BoxAlgorithm_KappaCoef_Setting3|
