CST112 Project #0

Create a VB form to read numeric values from a file.

Use a list box for multi-line output, as described below.  (There is no input from the form.)
Include the following buttons, with handlers to perform the following actions:

OPEN FILE:
	Pop up a dialog box to input a file specification.
	Assume the file specification is correct, and open the file for reading.

NEXT:
	Unless the file is at the end, read one line and convert it to a numeric value.
	Add the value to a running total, increase the count by one, and recompute the mean average.
	Then, display the output lines (in the listbox) similar to the following:
	
		The next value is   42.75
		It is greater than the average.
		The count is now   10
		The total is 386.0
		The average is   38.6

	If the value is within 1% of the average, say so instead.
 	
CLEAR:
	Clear the output area (listbox).
