======LUA Scripts======

=====TODO=====
==== Next Version ====
  * {{:uncheck.png}} Partition protocol data and functional code.

==== Current Version ====
  * {{:uncheck.png}} Find a simple way to test on real device data (this may be related to partition of the code).
  * {{:uncheck.png}} Define classes and values in a consistent way.

===== Response Tree Structure =====

Every tree has a root corresponding to a class. The classes and context of each are supposed to be defined dynamically in artefact.

==== Apparatus Classes ====

=== Tonoref2 ===

  * tonoref2_refractometer->osin/odxt->sph/cyl/axis
