//

// UserCounterType
//
// These enumerations describe how the counter works.
//
// MonotonicallyIncreasing	--	This describes a counter that will increment
//								by one each time some 'event' occurs.  An
//								example would be a counter that tracks the
//								number of memory allocations.  Each allocation
//								increments the number by one.
//
// MonotonicallyDecreasint	--	This describes a counter that will decrement
//								by one each time some 'event' occurs.  An
//								example would be a counter that tracks a limited
//								resource.  Each use of the resource decrements
//								the number by one.
//
// RandomIncreasing --			This describes a counter that will increase for
//								each 'event' that occurs, but by an undetermined
//								amount.  An example would be the total memory
//								allocated.  Each allocation would add it's size
//								to the counter, but each allocation being potentially
//								different, causes the counter to go up by a random
//								amount each time.
//
// RandomDecreasing --			This describes a coutner that will decrease for
//								each 'event' that occurs, but by an undetermined
//								amount.  An example would be a limited resource
//								that can be used in bunches.  Each use fo the
//								the resource would cause the number to descrease
//								by a random amount.
//
// Random --					This number can either go up, or go down.  An
//								example would be the total amount of available
//								memory, which can either go up (as memory is
//								free'd), or go down (as memory is allocated).
