renamed the property xcoord to xCoord. The setter/getter methods are named as getxCoord setxCoord getyCoord setyCoord so that it will show up as xCoord/yCoord in the wddx packet. if the getter methods are named as getXCoord , it will show up in the wddx packet as "XCoord" and not "xCoord"
in extractActivityObject method, changed it to get the hashtable key xCoord instead of xcoord, since flash is sending xCoord. ycoord is also changed to yCoord.
