Enable Multiple Routes to same component

[rodrigobacelli]

Here at work we needed to use some different pathnames and render the same component. The solution repeating s to was a little hard to maintain and understand the routes. Thinking in this, we developed a solution to render the same component using different paths separated by pipes.

Instead of using:

    <Route path="/" component={App}>
      <IndexRoute component={Index}/>
      <Route path = "myaccount" component={Account} />
      <Route path = "my-account" component={Account} />
      <Route path = "account" component={Account} />
    </Route>

Now we candeclare just one component:

    <Route path="/" component={App}>
      <IndexRoute component={Index}/>
      <Route path = "myaccount|my-account|account" component={Account} />
    </Route>

All tests has passed and I wrote some more to test if everything was working fine

We'd prefer not to extend the matching syntax in this manner. Instead, we want to do something more general purpose – some combination of #3098 and #3105, possibly configured on a per-route level. See discussion on those threads, and on #2286.
