public static void setProperties(Object object, Map map)

Sets the properties on the given object

public static void setProperty(Object object, String property, Object newValue)

public static void setProperty2(Object newValue, Object object, String property)

This is so we don't have to reorder the stack when we call this method. At some point a better name might be in order.

public static void setPropertySafe2(Object newValue, Object object, String property)

This is so we don't have to reorder the stack when we call this method. At some point a better name might be in order.
