Make generation reproducible

[pgrandinetti]

I needed to make the functionality of this package reproducible across multiple runs, to create a simulation that can be analyzed.

• Wrapped the functionalities into a class that has a random.Random object has as field.
• Maintained backward compatibility.
• Added unit test to check reproducibility.
• Changed environment to 3.7, though it shouldn't make a big difference.

Example usage

# old usage still works out-of-the-box
>>> import names
>>> names.get_full_name()
'David Johnson'
>>> names.get_full_name(gender='male')
'David Burkart'
>>> names.get_first_name()
'Marie'
>>> names.get_first_name(gender='female')
'Lida'
>>> names.get_last_name()
'Rossi'

# new functionality to reproduce the generation
>>> gen = names.Names(123)
>>> gen.get_full_name()
'Christopher Dryer'
>>> gen.get_first_name(gender='female')
'Virginia'
>>> gen2 = names.Names(123)
>>> gen2.get_full_name()
'Christopher Dryer'
>>> gen2.get_first_name(gender='female')
'Virginia'
>>>
