Generalized SEIR Epidemic Model (fitting and computation)

Updates:

• Examples updated.
• Minor bug corrected in the example dealing with the US cities ad states.
• The initial and final times are now chosen more easily by the user. This should greatly simplify the fitting procedure.
• The data from the Italian regions seems to be no longer available before June 2020
• Minor update for the functions used to fit multiple epidemic waves.
