Period.h

/*
	Author:		Mihir K Patel
	Purpose:	Following is an Abstract parent class of CalendarIO.h, and Menstrual_Guide.h and a Header file for the Period.cpp.
			This class provides important data  members and member functions which are mind of this OOP project.
			Some of the immportant member functions are fix_user_string(string) which removes the numbers and punctuation marks;
			check_choice(), checks the entry of Y or N, distance(int, int, int), a helper-recursive function which calculates the
			minimum for array values passed in until the condition in the did_you_mean_this(string, string, size_t, size_t) function
			return the total numbers of edits. did_you_mean_this(string, string, size_t, size_t) is the edit distace algorithm,
			which finds the minimum distance for strings the user put in, and the string that iterator point to in map in subclass
			Menstrual_guide.h. Lastly there is a pure virtual ostream>> operator which gives each class an ability to
			print their own local ostream>> using Period.h's data members.
