Description: Functions to impute large gaps within multivariate time
        series based on Dynamic Time Warping methods. Gaps of size 1 or
        inferior to a defined threshold are filled using simple average
        and weighted moving average respectively. Larger gaps are
        filled using the methodology provided by Phan et al. (2017)
        <DOI:10.1109/MLSP.2017.8168165>: a query is built immediately
        before/after a gap and a moving window is used to find the most
        similar sequence to this query using Dynamic Time Warping. To
        lower the calculation time, similar sequences are pre-selected
        using global features. Contrary to the univariate method
        (package 'DTWBI'), these global features are not estimated over
        the sequence containing the gap(s), but a feature matrix is
        built to summarize general features of the whole multivariate
        signal. Once the most similar sequence to the query has been
        identified, the adjacent sequence to this window is used to
        fill the gap considered. This function can deal with multiple
        gaps over all the sequences componing the input multivariate
        signal. However, for better consistency, large gaps at the same
        location over all sequences should be avoided.
