Make SuruBarController available externally

[AllyMarthaJ]

Hi there!

I'm attempting to make use of the multithreaded features of this library, and I encountered an issue where I couldn't actually reference the type SuruBarController. That is, I'm passing in the following type to a thread I'm creating:

type ThreadData = ref object
    y*, xInc*, yInc*: float
    offsetY*: int
    opts*: GraphOpts
    imageAddr*: ptr Image
    bar*: ptr SuruBarController

Creating a thread like so:

    var bar = initSuruBarThreaded()
    bar[0].total = size

    if opts.showProgress:
        bar.setup()

...


        let data = ThreadData(
            offsetY: offsetY,
            y: y,
            xInc: xInc,
            yInc: yInc,
            opts: opts,
            imageAddr: imageAddr,
            bar: bar
        )
        threads[i].createThread(processRow, data)

But with the current iteration, this doesn't work because SuruBarController is inaccessible externally.

Was wondering if it were possible to change the definition from:
SuruBarController = object to SuruBarController* = object

Cheers!

Sorry for just getting back to this now. I will have to take a moment to reacquaint myself with the library and look into this.
