/* 

This program manages"simulates" messages from a varitey of different type of communication channels. Phone, email and facebook

It contains a class of persons contact which is conatined in array, mssages are contained in an AVL tree in. 
all structures are managed with a class that contained two AVLs and a contact list.
operator overloading was used in all classes to make the implientaion eaiser
