I2P daily graph extraction framework

README

Save I2P-generated bandwidth and other statistics to a set of PNG files.
Each file is a png graph of some I2P stat for the given day.

I2P stat can be useful for monitoring networking reliability on host 
(assuming that I2P itself is stable).

Usage:
* set parameters in the beginning of Makefile
* chmod +x auxilary scripts
* `make` will start downloading the pictures
