A collection of classes intended for use in optimising the performance of your code.
Currently this consists of four parts:
GSTicker ... where knowing the time to the nearest second is enough, using GSTicker allows you to avoid the overheads of a system call to query the system clock.
GSCache ... provides a general purpose caching class to let you keep data in memory rather than slowly retrieving it from a database or other disk-based source.
GSSkipMutableArray ... an array whose storage layout is designed for fast insertion/removal of items from the middle of the array.
GSThroughput ... provides a mechanism to record throughput/performance statistics so that you can keep track of peak activity of a long running program.
