fluorescence-anisotropy-vs-strain-modelling-v1.1.0

This release updates the initial release by improving the uncertainty of the exponential model and formatting of the
figures. The confidence intervals are now represented by a shaded area, instead of dotted lines. The modelling is now
performed with the 'lmfit' python package instead of the 'SciPy' package. Additionally, the uncertainty in the model is
reduced by applying a boundary condition of $a = c - r_0$, where $r_0$ is the anisotropy of the unstretched film.
The exponential term has a value of 1 for a true strain value of 0, therefore the y-intercept is equal to c - a.
Consequently, the boundary condition stated above can be applied. The new equation used for exponential modelling is
therefore:

$$r = -(c - r_0)e^{-b\epsilon} + c$$

where r is the fluorescence anisotropy of the film, $\epsilon$ is the true strain of the film, $r_0$ is the fluorescence
anisotropy of the unstretched film, and b and c are fitting parameters.
