Write a program in OCaml, that will construct a record that will have fields for a name, a score, and a letter grade.

The program will display a message asking the user for a name which will get entered into the name field.

It will then ask the user for a score, in the range if 0 through 100. These will be integers. I should be able to enter as many scores as I wish.

The program should then calculate the average as a floating point number, and store the average in the score field.

Then it will determine the letter grade based on the following:

90 >= score A

80 >= score < 90 B

70 >= score < 80 C

60 >= score < 70 D

score < 60 F

The grade then is entered into the grade field. Then the fields in the record are printed out to the screen.
