SampleEntropy

Calculates the sample entropy of a track record. Sample entropy is an improvement of the approximate entropy and should produce accurate results
for timeseries of smaller length like historical returns of strategies

Contains performance analysis metrics of track records including entropy-based
correlation and dynamic beta based on a state/space algorithm. The normalized sample entropy method
has been implemented which produces accurate entropy estimation even on smaller datasets.
On a separate stream, trades from the five major assets classes and also
functionality to use pricing curves, rating tables, Credit Support Annex and add-on tables. The
implementation follows an object oriented logic whereby each trade inherits from
more abstract classes while also the curves/tables are objects. Furthermore, odds calculators
and P&L back-testing functionality has been implemented for the most widely used betting/trading
strategies including martingale, 'DAlembert', 'Labouchere' and Fibonacci. Back testing has also been included for the 'EuroMillions',
the 'EuroJackpot', the UK Lotto, the Set For Life and the UK 'ThunderBall' lotteries.
Furthermore, some basic functionality about climate risk has been included.
