def drawTree(height, color):
    
    ''' 
    This function draws a tree of a given height that consists of a rectangular brown bark and a top comprised of three triangles of a given color stacked on top of each other.
    The bottom left corner of the bark will be at current location of the turtle, making no assumptions about the orientation of the turtle.
    After drawing the tree the turtle will be returned to its original position and oriented at 0 degrees 
    All other parameters such as the width of the tree and the length of the bark are chosen so that the tree is well proportioned: a taller tree is wider and has a thicker and taller bark.
