How to use the oommfc.drivers.driver.Driver function in oommfc

import oommfc as oc
from .driver import Driver


class HysteresisDriver(Driver):
    def _script(self, system, **kwargs):
        # Save initial magnetisation.
        m0filename = 'initial_magnetisation.omf'
        system.m.write(m0filename)

        meshname = system.m.mesh.name
        systemname = system.name
        Hmin = kwargs["Hmin"]
        Hmax = kwargs["Hmax"]
        n = kwargs["n"]

        mif = oc.util.mif_file_vector_field(m0filename,
                                            'initial_magnetisation',
                                            'main_atlas')
        mif += oc.util.mif_vec_mag_scalar_field('initial_magnetisation',
                                                'initial_magnetisation_norm')

class TimeDriver(Driver):

    Only attributes in ``_allowed_attributes`` can be defined. For details on
    possible values for individual attributes and their default values, please
    refer to ``Oxs_TimeDriver`` documentation (https://math.nist.gov/oommf/).

    Examples
    --------
    1. Defining driver with a keyword argument.

    >>> import oommfc as oc
    ...
    >>> td = oc.TimeDriver(total_iteration_limit=5)

    2. Passing an argument which is not allowed.

class MinDriver(Driver):
    """Energy minimisation driver.

    Only attributes in ``_allowed_attributes`` can be defined. For details on
    possible values for individual attributes and their default values, please
    refer to ``Oxs_MinDriver`` documentation (https://math.nist.gov/oommf/).

    Examples
    --------
    1. Defining driver with a keyword argument.

    >>> import oommfc as oc
    ...
    >>> md = oc.MinDriver(stopping_mxHxm=0.01)

    2. Passing an argument which is not allowed.
