mistakes in the documentation of the FitContributor

I was struggling to use the FirContributor for one of my apps and I believe the are some mistakes in this documentation: https://developer.garmin.com/connect-iq/api-docs/Toybox/FitContributor.html

1. createField needs to be called on a session created by session = ActivityRecording.createSession

2. Fit.MESG_TYPE_RECORD does not work because there is no `Fit` in the import/use statements. It has to be FitContributor.MESG_TYPE_RECORD or using Toybox.FitContributor as Fit;
   1.  https://developer.garmin.com/connect-iq/core-topics/activity-recording/#fitdeveloperfields mentions a similar line that is confusing:
      mNamasteField = session.createField("current_namastes", NAMASTE_FIELD_ID, FitContributor.DATA_TYPE_FLOAT, { :mesgType=>Fit.MESG_TYPE_RECORD, :units=>"N" });
      
      To make it clearer I would suggest in both cases ether to use using Toybox.FitContributor as Fit; and then use `Fit` everywhere OR even better just use `FitContributor` everywhere
