// Register Development Function Version 1.0
	
	/*
		A. Description
			Register is used to check if the user inputs the correct values in the 
			correct way and to show the user the error messages.
		
		B. Parameters
			1. array
			Contains all input fields what should have a real value.
			Usage ex: 'username, password'
		
			2. length
			Contains all input fields what should have a minimum and a maximum length.
			Useage ex: "username:password=6"
		
			3. matches
			Contains all input fields what should match.
			Usage ex: "password:passwordAgain"
		
			4. groups
			Contains all input fields or select options what should be work as one.
			Usage ex: "year:month:day=date"
			
			5.chars
			Contains all input fields what should enable special chars
			Usage ex: username=@;#,email=@;! OR username=all, password=all
			
		C. Returns
			1. True
			If "errors" array is NULL.
			
			2. False
			If "errors" array is NOT NULL.
			
		D. General Usage Rules
			1. If you want to use multiple sets then you should use add ", " (comma+space) after the first set.
			Usage ex: username:password=6, email=3, year:month:day=3
			
		E. Extra features
			1. Email Validation
			Usage ex: Input id should be "email"
			
			2. Error Messages for error types
			
			3. Style change on Error
