 * Twelfth version. Updated dependencies, switched to the [Float] only versions of the FuncRep and inner functions. Introduced a new textual command line
 argument that allows to choose which metrices (called \"properties\") to use from uniqueness-periods-vector-properties package. Made a package
 containing also two libraries which shares the common functions.
