=======

This repository hosts a helper class to programmatically format an array of records into a tree structure.

Example:

From this set of records:

```

[

  [

    'aggregate1' => '2017-07-01',

    'aggregate2' => 'foo',

    'metric1' => 51,

    'metric2' => 19,

    'metric3' => 7,

  ],

  [

    'aggregate1' => '2017-07-01',

    'aggregate2' => 'foo',

    'metric1' => 33,

    'metric2' => 13,

    'metric3' => 37,

  ],

  [

    'aggregate1' => '2017-07-02',

    'metric1' => 3,

    'metric2' => 35,

    'metric3' => 22,

  ],

]

```

We should get this:

```

[

  '2017-07-01' => [

    'foo' => [

      'metric1' => 84,

      'metric2' => 32,

      'metric3' => 44,

    ],

  ],

  '2017-07-02' => [

    'metric1' => 20

    'metric2' => 29

    'metric3' => 27

  ]

]

```

Here the metrics are summed, but it should be allowed to provide an aggregate function
