 This function will check to see if a function exists in firmware (native, internal) or has been defined in the current script context (custom, user-defined).  It is useful if a script needs to determine if it is being run on an older version of the firmware that might not have some of the newer functions. It can also be used for controlling flow in scripts that define custom functions depending on certain conditions or [[include|included]] files. This function will check to see if a function exists in firmware (native, internal) or has been defined in the current script context (custom, user-defined).  It is useful if a script needs to determine if it is being run on an older version of the firmware that might not have some of the newer functions.
