Patch for bar objects

[Michael Goffioul]

Hi,

I'd like to propose the following patch, which does 2 things:
1) put actual bar creation into a separate function to make it easier for
a graphic backend to hook up its own bar objects
2) compute the bar/group width according to the minimum X step
(IIRC, this is similar to Matlab way of doing); otherwise something
like

     bar([1 3 3.5 6 8 9], rand(6,5))

gives pretty bad results.

Michael.

    * plot/__bar__.m: put bar creation code into separate function
    to allow easy hook up from other graphic backends

    * plot/__bars__.m: new function containing bar creation code
