//
// Level description
//
// None - Function is no threat at all. It doesn't constitute
// an threat to either users or the system and has no
// known side effects
//
// Nuisance - Abuse of this command can cause a nuisance to the
// region operator, such as log message spew
//
// VeryLow - Extreme levels ob abuse of this function can cause
// impaired functioning of the region, or very gullible
// users can be tricked into experiencing harmless effects
//
// Low - Intentional abuse can cause crashes or malfunction
// under certain circumstances, which can easily be rectified,
// or certain users can be tricked into certain situations
// in an avoidable manner.
//
// Moderate - Intentional abuse can cause denial of service and crashes
// with potential of data or state loss, or trusting users
// can be tricked into embarrassing or uncomfortable
// situationsa.
//
// High - Casual abuse can cause impaired functionality or temporary
// denial of service conditions. Intentional abuse can easily
// cause crashes with potential data loss, or can be used to
// trick experienced and cautious users into unwanted situations,
// or changes global data permanently and without undo ability
// Malicious scripting can allow theft of content
//
// VeryHigh - Even normal use may, depending on the number of instances,
// or frequency of use, result in severe service impairment
// or crash with loss of data, or can be used to cause
// unwanted or harmful effects on users without giving the
// user a means to avoid it.
//
// Severe - Even casual use is a danger to region stability, or function
// allows console or OS command execution, or function allows
// taking money without consent, or allows deletion or
// modification of user data, or allows the compromise of
// sensitive data by design.
