**Header:** `ClikaRT/graph/input_specs.h`

The shape profile of ONE input: the range of shapes the compiled graph is prepared for, as three extent lists with one entry per dimension. [`min`](./ShapeProfile.md#min) is the smallest shape the input will be fed, [`max`](./ShapeProfile.md#max) the largest, and [`opt`](./ShapeProfile.md#opt) the typical one, which the compiled graph is specialized to; [`min`](./ShapeProfile.md#min)/[`max`](./ShapeProfile.md#max) are validated and recorded. For a fixed shape use the single-shape constructor (min == opt == max).
