//Program 1

//For this program the main objective is to create a all in one system
//That stores all data from different learning management systems
//And tries to organize it into one single one. 
//There will be 5 classes that focus on storing different items like emails, calendar, grades etc.
//The data structure used for this program will be a linear linked list of arrays.
//This is a good data structure which can keep everythign fairly organized. 
//I implimented insert, display, search, and remove for all 3 of my classes.
//Remove function sometimes has hickups but works fairly well.
