Support more than one path param

The library does not support more than one path parameter being used (e.g. /:path/:path2) for a single route, otherwise it gives a gives a param error during startup.

Maybe you set two conflicts path like these:

router.GET("/hello/:name", Hello)
router.GET("/:name/:word", MultiParams)

The path /:name is conflict with existed path /hello. Use more clear paths will fix the panic:

router.GET("/hello/:name", Hello)
router.GET("/multi/:name/:word", MultiParams)

Full codes is in examples

@buaazp I only have one route, and it seems to still fail. I'll try to put together a test case.

You can paste a simple badcase here to reproduct.
