/*
*
* Hi and thanks for taking the time to check out WSL code.
*
* Please, don't hesitate to:
*
* - Report bugs and issues.
* - Contribute: code, reviews, ideas and design.
* - Point out stupidity, smells and inconsistencies in the code.
* - Criticize.
*
* If you want to contribute, please consider these general "guide lines":
*
* - Small patches will be always welcome. Large changes should be discussed ahead of time.
* - That said, don't hesitate to delete code that doesn't make sense or looks redundant.
* - Feel free to create new functions and files when needed.
* - Avoid over-commenting, unless you find it necessary.
* - Avoid using 'switch' and 'for'. I hate those.
*
* Coding Style :
*
* - Readable code.
* - Clear indentations (tabs: 8-char indents).
* - Same name convention of WordPress: those long long and self-explanatory functions and variables.
*
* To keep the code accessible to everyone and easy to maintain, WordPress Social Login is programmed in
* procedural PHP and will be kept that way.
*
* If you have fixed, improved or translated something in WSL, Please consider contributing back to the project
* by submitting a Pull Request at https://github.com/miled/wordpress-social-login
*
* Grep's user, read below. Keywords stuffing:<add_action|do_action|add_filter|apply_filters>
*
* If you are here just looking for the hooks, then refer to the online Developer API. If it wasn't possible to
* achieve some required functionality in a proper way through the already available and documented WSL hooks,
* please ask for support before resorting to hacks. WSL internals are not to be used.
* http://miled.github.io/wordpress-social-login/documentation.html
*
* If you want to translate this plugin into your language (or to improve the current translations), you can
* join in the ongoing effort at https://www.transifex.com/projects/p/wordpress-social-login/
*
* Peace.
*
