Empymod

--------------------------------------

**2017-03-11**

- Change default filter from ``key_401_2009`` to ``key_201_2009`` (because of
warning regarding 401 pt filter in source code of ``DIPOLE1D``.)

- Since 06/02/2017 installable via pip/conda.

- Bug fixes

---------------

**2017-02-02**

- New routine:

- General modelling routine ``bipole`` (replaces ``srcbipole``): Model the EM
field for arbitrarily oriented, finite length bipole sources and receivers.

- Added a test suite:

- Unit-tests of small functions.
- Framework-tests of the bigger functions:

- Comparing to status quo (regression tests),
- Comparing to known analytical solutions,
- Comparing different options to each other,
- Comparing to other 1D modellers (EMmod, DIPOLE1D, GREEN3D).

- Incorporated with Travis CI and Coveralls.

- Internal changes:

- Add kernel count (printed if verb > 1).
- ``numexpr`` is now only required if ``opt=='parallel'``. If ``numexpr`` is
not found, ``opt`` is reset to ``None`` and a warning is printed.
- Cleaned-up wavenumber-domain routine.
- theta/phi -> azimuth/dip; easier to understand.
- Refined verbosity levels.
- Lots of changes in ``utils``, with regards to the new routine ``bipole``
and with regards to verbosity. Moved all warnings out from ``transform``
and ``model`` into ``utils``.

- Bug fixes


v1.1.x
""""""

------------------------------

**2016-12-22**

- New routines:

- New ``srcbipole`` modelling routine: Model an arbitrarily oriented, finite
length bipole source.
- Merge ``frequency`` and ``time`` into ``dipole``. (``frequency`` and
``time`` are still available.)
- ``dipole`` now supports multiple sources.

- Internal changes:

- Replace ``get_Gauss_Weights`` with ``scipy.special.p_roots``
- ``jv(0,x)``, ``jv(1,x)`` -> ``j0(x)``, ``j1(x)``
- Replace ``param_shape`` in ``utils`` with ``_check_var`` and
``_check_shape``.
- Replace ``xco`` and ``yco`` by ``angle`` in ``kernel.fullspace``
- Replace ``fftlog`` with python version.
- Additional sine-/cosine-filters: ``key_81_CosSin_2009``,
``key_241_CosSin_2009``, and ``key_601_CosSin_2009``.

- Bug fixes
