Variable naming may be ambigous

[jbuisine]

In code function : https://github.com/prise-3d/rawls_api/blob/devel/api.py#L16-L31, CSV_file variable has Class naming convention and can bring ambiguity.

It's better to always use same naming convention for variable and Classes:

class CSVFile():
    pass
class MyClass():
    pass

instance = MyClass()
csv_file_instance = CSVFile()
