Description:

def upload(self, filepath, service_path, remove=False):
        '''
        "Upload" a file to a service

        This copies a file from the local filesystem into the ``DataService``'s
        filesystem. If ``remove==True``, the file is moved rather than copied.

        If ``filepath`` and ``service_path`` paths are the same, ``upload``
        deletes the file if ``remove==True`` and returns.

        Parameters
        ----------
        filepath : str
            Relative or absolute path to the file to be uploaded on the user's
            filesystem

        service_path: str
            Path to the destination for the file on the ``DataService``'s
            filesystem

        remove : bool
            If true, the file is moved rather than copied
