I was wondering if the fromstring function could be expanded to include ascii 
strings. Right now, I'm considering reading my messy file, creating a neatly 
formatted string, writing that string back into a temporary file, and then 
using the fromfile function. It would be so much nicer to just create the 
array from the string itself.
