 * Each major release beyond V1 (such =v2[+].a.b) must provide unique import path such as `github.com/quobyte/api/vX`
   * To get around this issue, we always use v1.x.x (**NEVER** make v2 release)
   * Further, each `*.go` file must have a `package XYZ` statement as the first line and must be placed into `XZY`
