/**
 * Adds a new line range layer.
 *
 * Creates a context in which you can create bindings using aesthetic attribute properties invocation:
 * ```
 * lineRange {
 *    x(source("time")) // mapping from data source to 'x' coordinate
 *    borderLine.color(Color.BLUE) // setting of constant color value
 * }
 * ```
 *
 *  ### Aesthetic attributes:
 *
 *  Positional:
 *
 *  - [ x][LineRangeContext.x]
 *
 *  Initial mappings to positional attributes are inherited from the parent [PlotContext] (if they exist).
 *
 *  Sub-positional:
 *  - [yMin][LineRangeContext.yMin] - lower bound of the error bar
 *  - [yMax][LineRangeContext.yMax] - upper bound of the error bar
 *
 *   Non-positional:
 *  - [alpha][LineRangeContext.alpha] - layer alpha, of the type [Double], mappable
 *  - [borderLine.color][BorderLineSubContext.color] - color of the borderline, of the type [Color], mappable.
 *  - [borderLine.width][BorderLineSubContext.width] - width of the borderline, of the type [Double], mappable.
 *  - [borderLine.type][BorderLineSubContext.type] - type of the borderline, of the type [LineType], mappable.
 *
 *  // TODO write about borderLine invocation?
 *  ```
 *  lineRange {
 *     borderLine {
 *        color(Color.RED)
 *        type(LineType.DOTTED)
 *     }
 *  }
 *  ```
 *
 * // TODO move data overriding to args
 *  By default, the dataset inherited from the parent [PlotContext] is used,
 *  but can be overridden with an assignment to the [data][LineRangeContext.data].
 *
 *  // TODO refer to bindings?
