Description: Provides S3 vector types for functional data represented
        on grids, in spline bases, or via functional principal
        components. Supports arithmetic and summary methods, plotting,
        derivation, integration, smoothing, registration, and data
        import/export for these functional vectors. Includes
        data-wrangling tools for re-evaluation, subsetting,
        sub-assignment, zooming into sub-domains, and extracting
        functional features such as minima, maxima, and their
        locations. Enables joint analysis of functional and scalar
        variables by integrating functional vectors into standard data
        frames.
