Add statistics

README.md

+# ZerfiXOR
+
+Very simple exploit launcher in < 200 lines of code.
+
+Offers:
+
+* Configurable Amount of workers
+* Statistics output
+* Automatic exploit dicovery
+* State preserving
+
+Start with: `python3 main.py`
+
+## Adding an exploit
+To add an exploit, just copy it into the `exploits` folder **and set the eXecute bit**.
+The exploit can be written in any language, but needs a shebang line.
+
+## Align for CTF
+Adjust the `changeme.py` file to use the tool in a ctf.
+
+## Statistics
+To receive statistics, just do a `python3 statistics.py` (also works will launcher is running).
+
+It will give you something like:
+
+```
