Time Series Metric Extraction for Application Behaviour Modeling

Starting from univariate signals coming from test workloads run under different
restriction a consistent single-dimensional signal parametrization method through
piecewise-linear functions was defined and packaged in a ready-to-use suite.
The results could be used to characterize the signals and measure their reactions
to changes in computing and/or network resources.
More work is still needed for the multidimensional case.
