The current package contains types that I require in projects where the type never changes, and used globally.

• Duration - Ability to store time.Duration over JSON and database.
• Numeric values - Ability to store and load int and uint family even when they are string for example.
• Bool - Ability to take boolean value as int, string and boolean and convert to bool type, with nil support.

• Add Tests for nil duration
• Add more test covers for nil duration
• Add More int and uint type support
