This function perform Cross-Validation k-Nearest Neighbors Cross-Validation.

1	my_knn_cv(train, cl, k_nn, k_cv)

`train`	The training input data frame.
`cl`	True class value of `train`.
`k_nn`	Integer representing the number of neighbors.
`k_cv`	Integer representing the number of folds.

A list of predicted class and a numeric with the cross-validation misclassification error cv-err.
