Nolds

Added
- more test cases for `sampen`
- `debug_data` parameter for most measures that allows to retrieve the data used for debug plots for logging and creation of custom plots

Changed
- `sampen` now takes functions for the `dist` parameter and not strings
- using something else than `rowwise_chebychev` for `dist` in `sampen` is now officially discouraged

Fixed
- naming confusion: "Euler" distance should be "Euclidean" distance
- typo in the name "Chebyshev"

Notes
- all changes mentioned above are backwards-compatible, but this compatibility will be dropped in the next version (since these are really stupid errors that I want to sweep under the rug :wink:)

Added
- `LICENSE.txt` is now part of the distribution
- specifies platform (any) and license (MIT) in `setup.py`
- loads `long_description` from `README.rst`

Fixed
- typo in `setup.py` regarding `extras_require`

Added
- Allows to use RANSAC as line fitting algorithm
- Uses classifiers in `setup.py`
- Adds requirements for the packages `future` and `setuptools`
- Adds custom clean command to `setup.py`

Changed
- Made support of both Python 3 and Python 2 official using the `future` package (Previous versions also supported Python 2 but did not state this and may have small performance issues.)

Fixed
- deprecation warning about `assertAlmostEquals` in test cases

Fixed
- Description on PyPI was broken due to formatting error in README.rst

Added
- exportable documentation with Sphinx
- this change log
- unit tests (`python -m unittest nolds.test_measures`)
- example code can be run with `python -m nolds.examples all`

Changed
- code formatted according to PEP8 (but with 2 spaces indent instead of 4)

Fixed
- wrong default plotting parameters for function `sampen`
