Generalized the method to set position from position data of the element
magnetized.

Using jquery drop event, the plugin cannot receive the drop from element
if this drop is outter from element magnetized.
CenterH, CenterV and Inner works fine.

Center at this moment uses centerh and centerv, but, will use his own
method.
Central configuration completed. Controlling if the element to be
dropped in the magnet area is bigger, more little, landscpe or portrait
shape. A lot of control!! Woo!
