@param temp CompositeGroupJunction which gets merged in this CompositeGroupJunction. This
       fusion occurs during creation of junction if the order in which the conditions of where
       clause arrival are such that condition1 tying region1 & region2 , condition 2 tying
       region 3 & region 4 and condition 3 tying region 3 and region 4. In such case , finally
       it should result in a single CompositeGroupJunction containing region1, region2 , region
       3 and region4 conditions and theire correspodning GroupJunctions if any.
