# Grade School

Given students' names along with the grade that they are in, create a roster
for the school.

In the end, you should be able to:

- Start with an empty school.
- Add a student's name to the roster for a grade
  - "Add Jim to grade 2."
  - "OK."
- Get a list of all students enrolled in a grade
  - "Which students are in grade 2?"
  - "We've only got Jim just now."
- Get a sorted list of all students in all grades.  Grades should sort
  as 1, 2, 3, etc., and students within a grade should be sorted
  alphabetically by name.
  - "Who all is enrolled in school right now?"
  - "Grade 1: Anna, Barb, and Charlie. Grade 2: Alex, Peter, and Zoe.
    Grade 3…"

Note that all our students only have one name.  (It's a small town, what
do you want?)

## Getting Started
For installation and learning resources, refer to the
[exercism help page](http://exercism.io/languages/ocaml).

## Installation
To work on the exercises, you will need `Opam` and `Core`. Consult [opam](https://opam.ocaml.org) website for instructions on how to install `opam` for your OS. Once `opam` is installed open a terminal window and run the following command to install core:

```bash
opam install core
```

To run the tests you will need `OUnit`. Install it using `opam`:

```bash
opam install ounit
```

## Running Tests
A Makefile is provided with a default target to compile your solution and run the tests. At the command line, type:

```bash
make
```

## Interactive Shell
`utop` is a command line program which allows you to run Ocaml code interactively. The easiest way to install it is via opam:
```bash
opam install utop
```
Consult [utop](https://github.com/diml/utop/blob/master/README.md) for more detail.

## Feedback, Issues, Pull Requests
The [exercism/ocaml](https://github.com/exercism/ocaml) repository on
GitHub is the home for all of the Ocaml exercises.

If you have feedback about an exercise, or want to help implementing a new
one, head over there and create an issue.  We'll do our best to help you!
