Hi Scott,

I noticed you did a lot of updates recently with these class - this  
is great. Form your comments in the code I have a hard time  
understanding what exactly a suffix array is (I'm an analytical  
chemist that mainly works with proteins, so pardon my ignorance ;-)   
Maybe you could add some more info in the source code to help better  
understand these classes?

Another question I have is why you are using calls such as fopen,  
fread, etc instead of the methods that Obj-C and Cocoa provide for I/ 
O. Mind you, I am just trying to understand the code, it's no  
criticism at all.


- Koen.
