Review comment:
       well in compression the overlap state only happens on a right matrix 
multiplication, but in federated i can already imagine it happening many times, 
if you want to convince me on another name it is fine, but i think having the 
same name would be nice.
   
   I guess you chose PART because it is a "PARTial aggregate value". I chose 
overlap because it is matrices that could be imagined to be on top of each 
other and added together to produce the result. I think that the name should 
reflect what it is, and if we have the same concept more places it should be 
called the same, that said i don't know what other ppl call it when they have 
distributed parts that could be reduced to the actual value.
