[src] minor changes within the MultivariateGaussianCharacteristicFunction tool : use of ot.dot is preferred to for loop
[test] minor update in test profiling: pretty print for easy readability
[test] updated profiling test : used default values of blockMin and blockMax to get correct values of pdf
[src] added a first version of cache mecanism for the computeDeltaCharacteristicFunction method. Ongoing work
[test] added test for validation of cache values. Ongoing work
