Helpers fo generating go codes

## Example 

```go

package main

import (

	"github.com/go-courier/codegen"

)

func main()  {

	file := codegen.NewFile("main", "examples/range-and-close/range-and-close.go")

 

    file.WriteBlock(

        codegen.Func(codegen.Var(codegen.Int, "n"), codegen.Var(codegen.Chan(codegen.Int), "c"), ).Named("fibonacci").Do(

            file.Expr("x, y := 0, 1"),

            codegen.For(file.Expr("i := 0"), file.Expr("i < n"), file.Expr("i++")).Do(

                file.Expr("c <- x"),

                file.Expr("x, y = y, x+y"),

            ),

            codegen.Call("close", codegen.Id("c")),

        ),

        codegen.Func().Named("main").Do(

            codegen.Define(codegen.Id("c")).By(codegen.Call("make", codegen.Chan(codegen.Int), file.Val(10))),

            codegen.Call("fibonacci", codegen.Call("cap", codegen.Id("c")), codegen.Id("c")).AsGo(),

            codegen.ForRange(codegen.Id("c"), "i").Do(

                codegen.Call(file.Use("fmt", "Println"), codegen.Id("i")),

            ),

        ),

    )

    

    file.WriteFile()

}

```

will generate file `examples/range-and-close/range-and-close.go`

```go

package main

import (

	fmt "fmt"

)

func fibonacci(n int, c chan int) {

	x, y := 0, 1

	for i := 0; i < n; i++ {

		c <- x

		x, y = y, x+y

	}

	close(c)

}

func main() {

	c := make(chan int, 10)

	go fibonacci(cap(c), c)

	for i := range c {

		fmt.Println(i)

	}

}

```
