Golang pointer helper.

Example

package main

import (
    "fmt"
    
    "github.com/roninzo/pointers"
)

func main() {    
    if p := pointers.New(25); *p == 25 {
        fmt.Println("p is a pointer to int 25")
    }
    if p := pointers.New(0); *p == 0 {
        fmt.Println("p is a pointer to int 0")
    }
    if p := pointers.New(0, pointers.Nilify); p == nil {
        fmt.Println("p is nil")
    }
}

// Output:
// p is a pointer to int 25
// p is a pointer to int 0
// p is nil
