TEST THINGY

--------------------------------
a.	Allow the user to specify a rectangle in two dimensions.  This rectangle should be aligned to an integer Cartesian grid.
b.	Allow the user to input as many points as they wish.  For each point entered, it should tell the user whether the point is inside the rectangle, on the boundary of the rectangle or outside the rectangle.
c.	Allow the user to exit once they have finished testing points.
--------------------------------

Problems:
	
	ai	Have a 2D array (integer cartesian).
	aii	User input coordinates in grid (2Darray).
	
	bi	User input points to test.
	bii	Test points between boundaries of rectangle.

	ci	Exit loop by user input.

-------------------------------

Main method:

	do While(not exit) 
		Take user input and give options for what to do:
		Exit, Set rectangle, Test points. 
		Switch for entering new points or exiting.
			Cases are exit, set rect, test point.
			Cases setRect and testPoint call functions.


Set rectangle:

	Create 2D array.
	User input 4 points.
	OPT: Display info about rectangle?

	EXTRA PROBLEM: 
		How to ensure points make a rectangle?
			| |
			| |
		       \   /
   			\ / 
			 V
 
		User input x axis as one value  
		Then y axis as two  
		Then x and two more y

		1  2 [3] 4  5 [6] 7  8
	
	


Test points:

	Function takes in created array from setRect.
	User input point.
	Test point is between x bounds and between y bounds.
	Print answer.
	OPT: How far from rectange is point?

Q2)
	a) scan in info
	b) loop to reject dupes (like in lottery task)
	c) maths (like in maths array task)
