Hi All,
I'm interested in developing a GUI front-end that does the equivalent of train_net.bin. Mainly what I want is a graph of training error and test error vs time or iterations as training progresses (along with possibly other statistics), with the opportunity to manually pause training, and save a snapshot and history of error vs iterations in a .csv file (as well as network weights).

My question is: if I were to develop this, would you wish me to submit a pull request that includes it under "tools" in caffe, or should I just create a completely separate project that uses caffe as a library? On the one hand, "make distribution" creates a nice library project to be linked to any application such as the application I envision. On the other hand, I think I may need to modify Caffe Solver so that it accepts an observer that receives notifications of statistics as training progresses.

Thanks for any thoughts,
Jim
