Implementation of the Complexity Invariant Distance (CID) measure as published in "A Complexity-Invariant Distance Measure for Time Series" by Gustavo E.A.P.A. Batista, Xiaoyue Wang and Eamonn J. Keogh. The authors address the complexity invariant of time series distance measures. That is, that time series with higher complexity tend to be further apart under current distance measures than pairs of simple objects. Given a complexity measure c and a distance measure d, the Complexity Invariant Distance for the two time series A and B is: d(A, B) * (max(c(A), c(B)) / min(c(A), c(B))).
