CUSTOM rule creation

custom: function(input, allow_rules, flag){

}

Parameters of custom validation

1. `input`: (Required) `String`. Is the input to test against the `allow_rules` 
2. `allow_rules`: (Optional) `Object`. Validation configuration
3. `flag`: (Optional) `String`. This method uses [RegExp](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp) to validate inputs. This parameter is the flag of the function. : new RegExp('-----', `flag`)

Create CUSTOM Rule

The second parameter of the function custom("",allow_rules) is used to create custom validation.

allow_rules = { 
    alphabets: {            // Pass Boolean false if alphabets are not allowed
       uppercase: Boolean, 	// default true 
       lowercase: Boolean  	// default true
    },
    numbers: {              // Pass Boolean false if numbers are not allowed
       range: String       	// default "0-9"
    },
    spaces: Boolean,   		// default true
    symbols: String, 		// default "", exapmle: '-_,' 
    str_length: {           // Object 
        min: Number,  		// default 1
        max: Number  		// default ""
    } 
}

// Pass the above configured rule as following
var str = "sample @123";
var result = custom(str, {spaces: false, symbols: "$#@"});
// Value of result is false as {spaces: false .. } and there is a space in str
