/**
 * Usage:
 *
 * On any node that participates in iOAM Trace.
 *
 * Step 1: Initialize this library by calling trace_init()
 * Step 2: Setup a trace  profile that contains all the parameters needed to compute cumulative:
 *         Call these functions:
 *         trace_profile_find
 *         trace_profile_create
 * Step 2a: On initial node enable the profile to be used:
 *          trace_profile_set_active / trace_profile_get_active will return the profile
 * Step 4: TBD
 *         trace_validate
