Package gang provides utilities to manage multiple goroutines.

## Synopsis

```go

package main

import (

	"context"

	"fmt"

	"github.com/hbagdi/gang"

)

func main() {

    // zero value is usable out of the box

	var g gang.Gang

    // add multiple functions which should be executed concurrently

	g.AddWithCtxE(func(ctx context.Context) error {

		fmt.Println("foo")

		return fmt.Errorf("err1")

	})

	g.AddWithChanE(func(done <-chan struct{}) error {

		fmt.Println("bar")

		return fmt.Errorf("err2")

	})

    // start execution of all the functions

	errCh := g.Run(context.Background())

    // collect errors from all the functions

	for err := range errCh {

		fmt.Println(err)

	}

    // execution finishes when errCh is closed

}

```
