[jacobkim9881]

Currently this repository has many chances to have many values. To be improved it needs new features but also it needs clean codes that has no difficulties to read its code. So the repositories improvement plan should be focused on refactoring. After re-structuring, re-defining variables adding new features will be more easy. Coding should be easy and reading it also should be easy too. Adding new features also are needed and will be proceed too.
