Create a new feature.
I added height and width properties to the NeedlePlot component and fragment. In the NeedlePlot component, I add height and width properties as well set them. In the NeedlePlot component, I gave the div and plot component these properties.
Also, I created tests for checking that these properties work as expected.
Closes #545
