It would be nice to consolidate this with xarray's current logic for getting virtual datetime variables (they should probably delegate to the accessor):

> I wonder, is there any way to register such an accessor with DataArrays that have a specific dtype? 

The simplest option is to raise `AttributeError` or `TypeError` in the constructor, e.g., 
```python
@xarray.register_dataarray_accessor('float_only')
class FloatOnlyAccessor(object):
  def __init__(self, parent):
    if parent.dtype.kind != 'f':
      raise TypeError('wrong dtype')
    self.parent = parent
```

```
>>> xarray.DataArray(1.5).float_only
<__main__.FloatOnlyAccessor at 0x8d51350>
>>> xarray.DataArray(1).float_only
TypeError: wrong dtype

I think the easiest way to do it would simply be to reuse xarray's accessor interface (i.e., `register_dataarray_accessor`) and then implement all the desired methods/properties.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,59720901
