In Guilz/rfret: Analyze FRET Binding Data

This internal function takes a model object from fit_binding_model or nls and returns a ggplot graph object of a binding curve figure.

1	make_one_figure(fit, experiment_name, binding_model, probe_conc = NULL)

`fit`	An `nls` object. The output of `fit_binding_model` can be used directly as input here.
`experiment_name`	The name of the corresponding experiment.
`binding_model`	The binding model used to fit the data.
`probe_conc`	The fixed concentration of probe molecule. This is ignored for models obtained with the hyperbolic and hill equations, but required for models obtained with the quadratic equation.
