[changed]

- `core.setup_config` function is changed to `config.setup_config`.

[added]

- added `utils.trace` decorator, which will **print** *function_name*, *args*, *kwargs* and *return value* when debug config key is True.
- new html-parsers ('html5lib', 'lxml') are supported for better webpages.
- html-parser is now defaulted to 'lxml'. You can use any through new `config.config` key called `parser`

[fixed]

- fixed issue while changing `user-agent` key cracked webpages. You can now use any browser's user-agent id and it will get exact same page downloaded.
- fixed issue in `generators.extract_css_urls` which was caused by `str` and `bytes` difference in python3.
- fixed issues in modules importing. (Thanks "**Илья Игоревич**").
- added `errorhandling` to required functions

- `init` function is replaced with `save_webpage`
- three new `config` automation functions are added -
- `core.setup_config` (creates every ideal config just from url and download location)
- `config.reset_config` (resets the configuration to default state)
- `config.update_config` (manual-mode version of `core.setup_config`)
- object `structures.WebPage` added
- merged `generators.generate_style_map` and `generators.generate_relative_paths` to a single function `generators.generate_style_map`
- rewrite of majority of functions
- new module `exceptions` added

- `url` is checked and resolved of any redirection before starting any work functions.
- `init` vars : `mirrors_dir` and `clean_up` were fixed which cleaned the dir before the log was completely written.
- `init` call now takes `url` arg by default and could raise a error when not supplied
- professional looking log entries
- rewritten archiving system now uses `zipfile` and `exceptions` handling to prevent errors and eventual archive corruption

- more redundant code
- modules are now separated based on type e.g. Core, Generators, Utils etc.
- new helper functions and class `structures.WebPage`
- Compatible with Python 2.6, 2.7, 3.6, 3.7
