# Functions for setting and clearing BYPASS values for visual properties,
# organized into sections:
#
# I. General functions for setting/clearing node, edge and network properties
# II. Specific functions for setting particular node, edge and network properties
#
# NOTE: The CyREST 'bypass' enpoint is essential to properly set values that 
# will persist for a given network independent of applied style and style 
# changes, and from session to session if saved.
