It mostly worked (even though there may be some issues when you want to use it as an xarray index).

Thanks, that's a nice trick! Supporting da.x_bounds['start'] will definitely be helpful! 

However, I am still concerned about 2D boundaries. Using the structured data type, 2D bounds will be an array of size (Nx,Ny,4) instead of (Nx+1,Ny+1). Although this matches the [CF convention](http://cfconventions.org/cf-conventions/v1.6.0/cf-conventions.html#cell-boundaries), it takes 4x memory and needs to be converted back to (Nx+1,Ny+1) for `pcolormesh()`. Not a big problem though. I will be happy to go this way if (Nx+1,Ny+1)-sized bounds cannot be implemented.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,242181620

Thanks! The idea of `NDIntervalIndex` mentioned at [pandas-dev/pandas#7640 comment](https://github.com/pandas-dev/pandas/issues/7640#issuecomment-71794646) seems powerful but too complicated to implement? Could there be a simpler way to hook the boundary attribute to DataArray?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,242181620
