Version 0.4

Whats new?
----------
Refractor most of the code.
Move input in the separate submodule.
Remove molecule plot type from ``rad-plot-tb2j.py`` script.

Major change in the logic of reading exchange files and templates.
Instead of using the class to load the file as before:

.. code-block:: python

    from radtools.exchange.model import SpinHamiltonianTB2J
    from radtools.exchange.template import ExchangeTemplate

    model = SpinHamiltonianTB2J(filename)
    template = ExchangeTemplate(template_filename)

Now one need to use read functions from input-output module:

.. code-block:: python

    from radtools.io.tb2j import load_tb2j_model
    from radtools.io.internal import load_template

    model = load_tb2j_model(filename)
    template = load_template(template_filename)

0.4.1
-----

Add ``--accuracy`` argument to the
``rad-extract-tb2j`` script.

0.4.2
-----

Add ``get_bond_vector()`` to the ``SpinHamiltonian``.

0.4.3
-----

Add reciprocal vectors to the ``SpinHamiltonian``.

0.4.4
-----

Add ``api_io`` interface.

There are two ways to import read functions:

.. code-block:: python

    from radtools.io.tb2j import load_tb2j_model
    from radtools.io import load_tb2j_model

.. code-block:: python

    from radtools.io.internal import
    from radtools.io import load_template

Add ``number_spins_in_unit_cell()`` property to the ``SpinHamiltonian``.

0.4.5
-----

Add ``reduced_parameters`` to the ``SpinHamiltonian`` class.

0.4.6
-----

Add exchange interface.

There are two ways to import read functions:

.. code-block:: python

    from radtools.exchange.model import SpinHamiltonian
    from radtools.exchange import SpinHamiltonian

.. code-block:: python

    from radtools.exchange.template import ExchangeTemplate
    from radtools.exchange import ExchangeTemplate

0.4.7
-----

Add High symmetry k-points.

Add methods to round up the exchange model.

0.4.8
-----

Add script for energy extractor.

0.4.9
-----
Add --legend_location option (removed in 0.5.7)
to the ``rad-plot-dos.py`` script.

0.4.10
------
Bugfix in ``rad-plot-dos.py`` script
