/**
 *The OperatorMap is a class responsible for storing the operators that have
 *been defined for use. The map holds the strings for operators, and their
 *corresponding node constructors. It has a function to allow the Node
 *associated with a string to be looked up, and a function to determine whether
 *a string is an operator or not.
 *
 *CONSTRUCTOR
 *OperatorMap()
 *        Note:The map is created in the Operator's constructor
 *
 *MEMBER FUNCTIONS
 *
 *Node* lookUpOperator(const string & operators)
 *        Allows the map to be searched for the operator, if present
 *        then the Node constructor for that time of operation will be called.
 *
 *
 *bool isOperator(const char & operators)
 *        Checks to see if the char is an operator. If it is returns true, else *        false.
 *
 *bool isTypeOperator(const string & typeString, const int & Precedence)
 *        Checks to see if type of operators with precedence searching for and string typeString
 *        are on the map
 *PRIVATE VARIABLES
 *
 *OperatorList myOperators
 *    List of operators in the map
