#! /bin/bash
#
# Look for all Tobii record segments into input folder ($1) to execute an ArGaze context file ($2) on each.
#
# For each Tobii record segment found a temporary context and pipeline files are created:
# - temporary context "segment" field is modified to bind on it,
# - temporary context "pipeline" field is modified to bind on a temporary pipeline file,
# - temporary pipeline "projection_cache" field is added to create or bind a "layers_projection.csv" file in segment folder,
# — if a "patch.json" file exist in the Tobii record segment, it merged to the temporary pipeline file,
# - then, ArGaze executes the temporary context from output folder ($3) to export all records into it,
# - finally, temporary context and pipeline files are deleted.
#
# Arguments:
# $1: folder from where to look for Tobii records
# $2: ArGaze context file
# $3: folder where to export processing outputs
# $4+: any other arguments are passed to "argaze load" command
