Hankel

--------------------
**Bugfixes**

- Fixed issue in Py3 in which dim=2 would not run the fast function (thanks `MuellerSeb <https://github.com/MuellerSeb>`_)

-------------------
**Enhancements**

- Added support for transforms with ``nu=-0.5`` (thanks `MuellerSeb <https://github.com/MuellerSeb>`_)

-------------------
**Bugfixes**

- Fixed Python 3 support from v0.3.4

---------------------
**Features**

- Added get_h function to aide in determining optimal h value for a given transformation.

**Enhancements**

- Added _get_series method to quickly retrieve the summed series for the integration.
- Two updated notebook examples.

**Bugfixes**

- Moved setting of N to avoid error.

---------------------
**Features**

- Some additional tools to determine accuracy -- quick calculation of last term in sum, and evaluated range.

**Enhancements**

- Default setting of N=3.2/h, which is the maximum possible N that should be chosen, as above this, the series truncates
due to the double-exponential convergence to the roots of the Bessel function.

**Bugfixes**

- Fixed error in cumulative sum when k is not scalar.

---------------------
**Enhancements**

- Documentation! See it at https://hankel.readthedocs.io
- Two new jupyter notebook demos (find them in the docs) by `francispoulin <https://github.com/francispoulin>`_

**Bugfixes**

- Fixed relative import in Python 3 (tests now passing), thanks to `louity <https://github.com/louity>`_
- Fixed docstring of SymmetricFourierTransform to have correct Fourier convention equation
- Fixed bug in choosing alternative conventions in which the fourier-dual variable was unchanged.
