… concentrations. Cleaned up functions in AssaySimulator.

…ance, and bias for different experimental parameters. The jupyter notebook was updated to reflect this. Two superfluous files were removed.

…other is superfluous.

-improving doctrings and a few comments
-removing extra factor of 100 from CV estimation
-added background fluorescence to data simulation when inner_filter=False

…tionality of AssaySimulator was slighlty changed so that instead of fitting a single binding free energy, multiple estimates of the free energy are returned instead.

…tted to is now outputed. Notebook updated accordingly.
