Class DotNotation

Util class containing a single method to collapse a multi-dimensional array into a single-dimensional array. Array keys are combined using a dot to separate levels of the array. For instance:

[
    'a' => [
        'x' => 'data1',
    ],
    'b' => 'data2',
]

[
    'a.x' => 'data1',
    'b' => 'data2',
]
