Comparison with embedded calc mode?

[npostavs]

I think it would be useful to compare this mode with embedded calc mode, in the README and perhaps explain why you would use this instead. I think one obvious difference might be support for spaces in variable names.

I have to admit I was not previously familiar with embedded mode, so I'm going to have to read up on it myself first, but I can definitely add a short comparison section to the readme. Feel free to submit a PR as well if you know what you'd like to see there.
