basic sprite display

function scene:enterScene( event )
    local group = self.view

    -- INSERT code here (e.g. start timers, load audio, start listeners, etc.)

    local sheetInfo = require("sprites.sheet_backgrounds") -- lua file that Texture packer published
    local myImageSheet = graphics.newImageSheet( "sprites.sheet_backgrounds.png", sheetInfo:getSheet() )

    local bgImage = display.newImage( myImageSheet , sheetInfo:getFrameIndex("img_Backdrop1"))

    --bgImage.x = 120
    --bgImage.y = 120

    group:insert(bgImage)

end
