*GET NIJ INTERCEPTS BY OCCUPANT TYPE AND LOAD TYPE*
===================================================

Looks up the Nij intercept value for a given occupant type (CRABI, Hybrid III variants) and axial/bending load type (tension, compression, flexion, extension). Use this worker to retrieve the normalisation intercept constants required before computing the Nij neck-injury criterion score.

When to use
-----------

Classification: **process**.

Tagged: ``crabi``, ``fmvss_208``, ``hybrid_iii``, ``injury_criteria``, ``intercept``, ``neck_injury_criterion``, ``neck_load``, ``nij``.

     - Type
     - Default
     - Required
     - Description
   * - Occupant Type
     - occupant_type
     - scalar
     - crabi_12_month_old_infant
     - 
     - Dummy/occupant category used to select the correct Nij intercept table; choose from CRABI 12-month infant or one of the Hybrid III family (3YO, 6YO, small female, mid-sized male); defaults to 'crabi_12_month_old_infant'.
   * - Load Type
     - load_type
     - scalar
     - tension
     - 
     - Axial or bending load direction for which the Nij intercept is needed (tension, compression, flexion, or extension); defaults to 'tension'.
   * - Scale
     - scale
     - text
     - 1
     - 
     - Optional scalar multiplier applied to the retrieved intercept value before output; leave at the default of 1 to return the unscaled standard intercept.
