#! /bin/bash
#
# Load json ArGaze context file ($1) then, look for all Tobii record segments into input folder ($2).
#
# For each Tobii record segment found:
# - context "segment" field is modified to bind on it,
# - context "pipeline" field is modified to bind on a temporary patched pipeline \
# resulting from the merging of the given pipeline and an optionnal "patch.json" file in Tobii record segment,
# - then, ArGaze executes the modified context from output folder ($3) to export all records into it,
# - finally, context is resetted and temporary patched pipeline is removed.
#
# Arguments:
# $1: ArGaze context file
# $2: folder from where to look for Tobii records
# $3: folder where to export ArGaze processing outputs
