Set attribute values programnatically won't change the visual of the progress wheel.

[boyserk84]

For example, if I call setBarColor( Color.parseColor("#e3a712"); in code, the bar color of the progress wheel won't visually change. The fix is quite simple, at least from the way I see it. It is basically due to barPaint object in ProgressWheel.java hasn't been updated with the new color value when setBarColor() is called.
