Setting up conditions and rules

• [x] Start with 100 coins of each type - Considering database saving and accessing data (Mysql or MongoDB) - Mysql and MongoDB cumbersome to setup so Just proceed with Cors Template.
• [x] Change should be made by utilizing the least amount of coins - Let the minimum amount process first
• [ ] The service should maintain the state of the coins throughout the transactions - Maintaining the state of the coins didn't work, it drain down to 0 and also the request for a change didn't work too cuz recursive is not behaving as expected. Need to fix.

These are the list of functionality worked:

Request for change - need bugfixing recursive call. Retrieve coins - after requesting a change of coins, coin state are draining down to 0, must fix recursive call it is affecting this functionality. Refill coins - working fine.
