New constructor

/**
 * @brief New Area trigger that checks for the occurrence of objects that have a bbox area
 * equal to or greater that the minimum and less than or equal to maximum.
 * @param[in] name unique name for the ODE Trigger
 * @param[in] source unique source name filter for the ODE Trigger, NULL = ANY_SOURCE
 * @param[in] class_id class id filter for this ODE Trigger
 * @param[in] limit limits the number of ODE occurrences, a value of 0 = NO limit
 * @param[in] minimum the minimum area to trigger an ODE occurrence in units of 
 * pixels. A value of 0 = NO minimum. 
 * @param[in] maximum the maximum area to trigger an ODE occurrence in units of 
 * pixels. A value of 0 = NO maximum.
 * @return DSL_RESULT_SUCCESS on success, DSL_RESULT_ODE_TRIGGER_RESULT otherwise.
