Ensure attenuation values (gas, cloud, rain, scintillation) are alway…

…s positive (#63)

* Ensure that attenuation values are positive

- The ITU models sometimes result in negative values (for certain inputs).
This PR guarantees that the attenuation values provided by the different models are always positive.

* Add flake8 comaptible formatting for itur.__init__.py

* Use all-close for Haversine functino test

- To prevent numerical errors

* Increase version number to 0.3.4

* Remove lru_cache dependency (not compatible with python 2.7)

Update codecov.yml to set target of 90% coverage

Update master for release of version 0.3.1 (#44)

* Add documentation for ITU-R P.1853 (#33)
* Improve validation documentation (#35)
* Improve validation statistics documentation. (#36)
* Fix bugs in P676 Revision (#40)
    - gaseous_attenuation_slant_path: pass correct values to radio_refractive_index in 'exact' case
    - n_ratio is n+1/n so equation for b need to divide not multiply to match the Rec.
    - gaseous_attenuation_slant_path: if index starts at 0 end is 922
    - Use the eqn in -12 to generate h_n as text is clear that h_n[0] should be 0 and h_n[921] should be 99.457 km.

* Add documentation to slant_path_attenuation exact equations (#41)
   - Add comments to reference equations to the recommendations 
   - Minor formatting changes in n_ratio to have the equation resemble those shown on the recommendation

* Fix bugs in P618 rain_cross_polarization_discrimination and site_diversity_rain_outage_probability (#43)
    - Fix typo in P618 Eqn 73 (rain_cross_polarization_discrimination)
    - Fix typo in P618 site_diversity_rain_outage_probability

* Fix constants in saturation_vapour_pressure to match ITU-R P.453-13 (#42)
* Add reccomendation ITU-R P.1623 (#34)
    Based on code provided by Luis Emiliani
     - Add base ITU-R P.1623
     - Add generic tests for ITU-R P.1623
     - Add documentation for ITU-R P.1623
     - Add ITU verification examples from rev 5.1

* Fix bugs in P840 (#45)
    - Pclw change files for load_data_interpolator
    - P840: Add probability 99.0 as per Rec/data files

* Run autoflake and autopep8 (#46)

Update to v0.3.0 (#27)

* Add validation examples to the documentation

* Update docs index page

- Improved table of contents
- Added links to indices and tables

* Improved documentation of utils.py

- Uniform description of functions
- Proper style for references to variables within the documentation
- Corrected several typos

* Harmonize description of function get_version

* Remove dependency of joblib and disk-cache

Using the disk-cache in joblib was actually impacting performance significantly, so I decided to remove completely the joblib dependency and have everything to be computed on the fly.

* Update installation of requirements.txt in documentation

* Improve documentation of __init__.py

Several typos and mistakes were fixed

* Update ITU-R P.1144 documentation to show code examples

* Fix indentation of change_version() function documentation

* Update contact e-mail

* Documentation fixes in models source files

- Remove  global __model from functions that do not modify the instance of __model
- Improve documentation style

* Remove documentation of module itur from the API documentation main documentation page

* Update .gitignore with files to build

* Improve format of automatically generated HTMLs in testing

* Include validation tables generated by automatic tests (used in documentation)

* Harmonize documentation of documentation for API models

- Add headers "Introduction" and "Module description"
- Include brief description + introduction section.

* Fix formatting of documentation for ITU-R P.453

- Add two equations on different lines and align on '='
- Indent variable definitions

* Update apidocs top-level descriptions.

* Add contributing information

* Add citation information in License and Contact sections.

* Update index page for ITU-Rpy.

* Add autolabel for section in Sphinx config

* Fix indentation bug in test_version.py

* Add contributing information to CONTRIBUTING.md

* Include tables with summary of recommendation versions in API docs

- Include code examples
- Include narrative explaining what and how validation is conducted

* Update format of index in documentation.

* Setup automatically fetches version from itur package

* Update README.md with latest version of packages implemented

* Fix documentation of change_version in ITU-840 with versions implemented

* Change URL of git-repository after transfer to personal account.

* Update units in test data CSV files

* Add script to create tables with versions implemented in ITUR-py

-Parses the ITU website for different recommendations
- Scrapes the links to PDFs, versions, and dates of publication for the different versions of the recommendation
- Determines what versions are implemented in ITUR-py and builds the table for the documentation

* Update validation.rst

* Add validation information to the README.md

* Add plotting capabilities with cartopy (default instead of basemap)

* Update documentation to reflect that plotting utilities in another module
