New function top.

New function 'top'

Thanks to this new function, it is now possible to view a list of the top ten (or any specified length) members.

Added function stats

Implemented function stats.

Now it is possible to compute stats for a user or for everybody

Minor bug fixing and new option added.

Fixed indentation error and added option help to the command show.
Now it's possible to view help screen by typing weeelab show help
(I always mistake while I try to view help screen because I type
weeelab show help, so, why not inserting this feature in the script? )

Changed script name.

v1.3.4

Changed script name to 'weeelab'

Algorithm improvements, strong code revision.

New features:

• Log file is not parsed by creating temp files, but now is loaded in a string array.
• Script automatically creates a backup copy of the log file and creates a new clean
  log file once a month.
• Implemented automatic log file backup on ownCloud shared folder (technically, we could
  now know who is in lab by reading that file from ownCloud shared folder c: )

Login and Logout with serial numbers and nicknames.

Special thanks to @Paso94 for implementing this new useful feature.
Now, if your name is something like "supercalifragilistichespiralidoso.martafazzoni",
don't worry, now you can use your serial number (numero di matricola senza la S davanti) to sign in.
You could even define one or more nicknames in the usersFile and use them to login or logout.

Bug fix.

v1.2

Update README.md

First working release

Now available, the first 100% (I hope) working version of the script.
Paper sign sheet reached its EOL.

First stable release

TODO

• Change login and logout time format to [gg/mm/aaaa hh:mm:ss]
  e.g:
  [25/12/2018 12:34] [26/12/2018 09:00] john.doe

• Print to log file the number of hours passed in lab after login and logout time.

• Implement an input string in function "logout" in order to save to log file a short
  description of work done [max length: about 128 characters]
