Overview

Build the style attribute for shape elements

Requirements:

Need to be able to take a string and break it up into style parts
A style part is usually a lowerCamel equals value pair (e.g. fontSize=12)
but sometimes it is just a singular value, (e.g. ellipse)
A string may also contain more then one style part separated by semi-colons
e.g. overflow=fill;fontSize=12;fontFamily=Helvetica

The purpose of this class is to build a style attribute with unique values and
to take inputs from either single key/value pairs or string following the
pattern previously described.
