--[[ Provides a simple color picker dialog
Usage:
colorPickerObject:Show(colorSelectedCallback[, r][, g][, b][, a])
*colorSelectedCallback - Called when a value is picked, signature: colorSelectedCallback(newR, newG, newB, newA)
*r - Optional starting red value (default: 1)
*g - Optional starting green value (default: 1)
*b - Optional starting blue value (default: 1)
*a - Optional starting alpha value, if no alpha value is provided the alpha slider is not shown, if one is provided the alpha slider is shown
