I think documentation could be improved.

Please note that I use Kallithea with Mercurial.
For my tests, I created a small Python script which write a simple log 
in a file. I though this file would be located in Kallithea binary 
directory as its path is "./log.txt".  In fact it was located in 
repository directory. It took me some time to realize it.
Maybe the documentation should notice it.

I used the following link for documentation : 
https://pythonhosted.org/Kallithea/setup.html "Hook management" section.
The "<|name>.<hook_type>|" assertion is either false or misleading. I 
think it should be replaced with "<hook_type>.<name>" as the first part 
of the hook description is the Mercurial hook type.
Also specifying the following may be helpful :
- The "<name>" part can be whatever we want (are there character 
restrictions ?) and is just a description (a reminder).
- "<hook_type>.<name>" must be unique
- "<hook_type> must be a Mercurial hook type. These can be found here : 
https://selenic.com/hg/help/hgrc
- Mercurial hook "arguments" like "$HG_NODE" are set in process 
environment variables by Kallithea before calling the hook.
- Kallithea sets an environment variable called "$KALLITHEA_EXTRAS" 
before calling the hook. This is especially useful to get the repository 
name in the hook process.

I have seen no trace in the console output noticing the execution of the 
hook. There might be a log somewhere but I have not found any log file 
anywhere.

Example hook descriptions might me helpful.

Hope this helps.

Nicolas
