Getting a blank picker

[rmdvector]

Using the latest from git from this repo, I get a blank picker instead of the expected wheels.
The picker is displayed using return ( <DatePicker onDateSelected={(date) => this.handleChange({}, date)} // no event param /> )

If I use v2.0.6 from npm I get a missing `format` variable.

Looks like the width comes up undefined, so I added minWidth to the style. Then height wasn't set so I added minHeight also and now it displays properly.
