Chaospy

==========================

ADDED:
* Added support for `openturns` Distributions (thanks Régis Lebrun).
* Added "Related Projects" section to root README with thanks and shout-outs.
* Added discrete distributions: Binomial, DiscreteUniform.
* Added recipe for stochastic dependent distributions:
`doc/recipes/dependent.rst`

CHANGED:
* Moved external interfaces to new submodule: `chaospy.external`:
SampleDist (KDE), OTDistribution (OpenTURNS), scipy_stats.
* Update Chaospy logo.

==========================

CHANGED:
* Replace `chaospy.bertran.operators.bertran_indices` with
`chaospy.bertran.bindex`:
* Faster execution by using more `numpy` for heavy lifting
* Moved `chaospy.{quad -> quadrature}` to finalize the refactor from v3.0.6.
* Documentation polish to `chaospy.quadrature`.

FIXED:
* Bugfixes in handling of three-terms-recursion

REMOVED:
* Remove `chaospy.quad.collection.probabilitic` as it is much easier to
implement from the user side.

==========================

ADDED:
* Added license to setup.py
* New quadrature rules (thanks to Nico Schlömer):
Gauss-Lobatto, Gauss-Kronrod, Gauss-Radau, Newton-Cotes.

CHANGED:
* Update CircleCI to test for Python versions 2.7.16, 3.6.8 and 3.7.3
* Update dependencies.
* Refactored `chaospy.quadrature`:
* Standardize quadrature interface.
* Lots of new docs.
* Move version number `chaospy.{version -> __init__}`.

REMOVED:
* Deprecating `chaospy.distributions.collection.raised_cosine` as `hyp1f2` is
no longer supported by `scipy`.
* Removing local `set_state` for Sobol indices and instead rely on
`numpy.random`'s random seed.

==========================

ADDED:
* Added new method `Dist._range` to override the lower and upper bound
calculations on some distributions.
* Added readme to setup.py

CHANGED:
* Adding caching to some of the functionality in `chaspy.bertran`
* Use new cached functions to improve on raw statistical moments of
multivariate Gaussian and multivariate Student-T distributions.
* Update polynomial output, as update to Bertran changes a few things in str
handle.

==========================

ADDED:
* Adding `chaospy.distributions.evauation` submodule to deal with graph
resolution.
* Added CircleCI tests for Python 2.7.15

CHANGED:
* Update CircleCI Python {3.6.2 -> 3.7.1}
* Some adjustments added to support Python 2.

REMOVED:
* Remove dependency to `networkx` (as `evaluation` now does this task).
* Deprecating `chaospy.distributions.cores` (as each distribution are now
locally defined in `chaospy.distributions.collection`)

==========================

FIXED:
* Fixes to CircleCI testing.
