## @code{__rerangecolumns} reranges the data sets depending on the input arguments.
## @code{matrix} is the data set matrix containing inputs and outputs (targets) in row order.
## This means for example: the first three rows are inputs and the fourth row is an output row.
## The second argument is used in the optimizing algorithm. This matrix contains informations about
## the description of the rows data of matrix.
## The third argument is used to be sure, rerange all the columns to the correct position.
