Fixed errors with TextMetric on some browsers

fix(TextMetric): Allow some metrics to be undefined
Some browsers do not currently report all metrics or required
that they be manually enabled by the user.  This fix allows
those specific metrics to be nil.

fix(TextMetric): Allow left metrics to be negative
Some browsers report the actualBoundBoxLeft as a negative number

Implemented feature to enable layout of rectangles

    * feat(Layout): New class implemented to layout rects

      Properties of a group of rects may be easily determined, e.g.
            - maxWidth
	          - maxHeight
		        Changes to a group of rects may be easily
      applied, e.g.
            - alignBottoms
	          - distributeHorizontally

    * fix(ClipPath): Clip has been renamed and now includes embedded
      Path

      BREAKING CHANGE:
            The Clip class has been renamed to ClipPath
	          The ClipPath class now requires a Path in the
            initializer
	          This addresses an issue where the Path would
            otherwise be rendered
	          in addition to being used for clipping

    * refactor(Path): Minor changes to separate path creation commands

      Separated the commands for generating a path from the commands
      for
            rendering the path
	          Added copy constructor

    * refactor(HttpHandler): Improved warning messages

    * feat(Rect): Added computed variables for width and height

    * feat(Rect): Added function to calculate union of two Rects

    * feat(Rect): Added functions to inflate a Rect

    * docs(all): Updated
