Hey, first of all, thank you very much for the great work.

I have a question about the InfluxDbWriteable derive. I updated the influxdb crate to 0.1.0 a few days ago.
I'm now using the InfluxDbWriteable derive instead of creating a write query. Everything works as it should, but I've noticed that the string field that I've marked as #tag is saved with quotation marks. (instead of saving abc, my influxdb instance saves the value "abc".
Is the a way to store the tag field without quotation marks?
