[FEAT] Detect Fixed / Hug / Fill dimensions

[drfarrell]

Currently the editor will display decimal values for calculated values. This is not particularly useful for showing how width and height are set up for an element.

Ideally, we're able to detect how those dimensions are calculated and displayed to the user.

This also ties in with #97

^ Partial fix in better styles.

Still need to determine size when they don't exist in CSS to be hug/fill/etc based on display type.
