This one is ready. @bergie review?

I only just looked at this, but it only seems to be addressing x/y metadata...what about other numeric data like width and height? I'd almost say to try to parse it as a number and if it fails then use a string. IIRC, the specific problem I was having was because it was x+width and y+height, so I guess it'll work if just one of them is numeric.

@davidmaxwaterman actually width and height shouldn't be specified at this level at all, see flowhub/the-graph#209

[davidmaxwaterman]

hrm, ok, but that makes me wonder what happens when you import the file again...is everything the same as it was before?

[forresto]

As it is now, width is always 72 and height is a function of the number of ports (something like Math.max(72, 8*n)).

ok, fair enough. thanks.
