Pytisean additions

tldr: jupyter notebook demo and additional functions added to nonlinear time series analysis package pytisean

Tisean is a C based command line software project for the analysis of time series with methods from based on the theory of nonlinear deterministic dynamical systems, or chaos theory. Although the toolbox is useful, users would prefer to use Python for their data analysis.

A base library, pytisean, existed which would pass and retrieve results from command line calls with Python. I expanded on it by adding functions to call specific core Tisean functions. Documentation for the relevant functions were copied. These changes made converting preexisting analyses to Python, or starting new ones more straightforward. Additionally, a Jupyter notebook was created to give an example of how to use pytisean to conduct a basic nonlinear time series analysis.
