-- meshoptions helper function

-- setting meshtypes to:
-- cross is x
-- plus is +
-- croplike is #
-- excroplike is # but the tips are more like a >
-- asterisk is like * but with three faces

-- horizonal is a bool operator - true makes it randomly positioned on x and y
-- height changes where the base of the plant is randomly pushed into the ground
-- size makes the plant 1.4 times bigger
