Init
As the name suggests, it is used to complete the default parameter settings of the project.

Initialize the framework settings.
Several steps are performed.
1. define the MD5_KEY value
2. set default timezone
3. enable session
4. add the setting_config value to the output.
5. load core_lang_index
