Accessing table by subscripting

[ahuang11]

I kind of expected this to work

import xarray as xr
import xarray_sql as xql

ds = xr.tutorial.open_dataset('air_temperature')

ctx = xql.XarrayContext()
ctx.from_dataset('air', ds, chunks=dict(time=100))
ctx["air"]

But instead, I needed to do:

import xarray as xr
import xarray_sql as xql

ds = xr.tutorial.open_dataset('air_temperature')

ctx = xql.XarrayContext()
ctx.from_dataset('air', ds, chunks=dict(time=100))
ctx.table("air")

I also expected .chunks to work.

ctx.table("air").chunks

I'll work on automatic dimension inference during to_dataset.
Will include:

• Analysis of current to_dataset behavior
• Implementation of automatic dimension inference
• Tests for the new functionality
