Templates within Echo

The Echo framework does provide a facility for custom rendering which is based on the echo.Renderer interface. This interface stipulates that implementations have a method Render which will perform the rendering of data. With this convention, we are able to take what we learned about Go templates and apply those templates to implement a custom echo.Renderer that is capable of rendering HTML templates back to the caller. The following is a very minimal example of an echo.Renderer implementation that we have implemented in $GOPATH/src/github.com/PacktPublishing/Echo-Essentials/chapter8/handlers/reminder.go:

type CustomTemplate struct {
        *template.Template
}

func (ct *CustomTemplate) Render(w io.Writer, name string, data interface{},
        ctx echo.Context) error {
        return ct.ExecuteTemplate(w, name, data)
}

Within this code block, we are creating a CustomTemplate structure which is a template.Template type. Within the Render method, that is required of...
