Merge branch 'doc' into dev

This adds documentation options using sphinx.
The doc still mostly needs to be written

+Example of how unisync works
+============================
+
+Let's say you have the following structure::
+
+        $ tree .
+        .
+        ├── big_file
+        └── folder
+            ├── file
+            └── other_file
+
+If you only want to synchronise `folder` and its content on your laptop the following will be automatically generated::
+
+        $ tree .
+        .
+        ├── big_file -> ../.data/big_file
+        └── folder
+            ├── file
+            └── other_file
+
+`big_file` is now a symbolic link and by mounting the remote directory you can still seemlessly access `big_file` through the network.

+.. unisync documentation master file, created by

+
+Documentation for unisync
+=========================
+
+Unisync is a data synchronising tool built around `unison`_ and expending on it.
+
+Unisync tries to solve two problems that are often solved separately but never together :
+
+* Keeping your data synchronised between multiple machines (through a central server), examples of this are rsync and of course unison.
+* Being able to access and edit files stored on your server without having to download them, the gui interface of nextcloud for example.
+* And of course I want to be able to do all of this without ever having to leave my terminal.
+
+Unisync solves this problem by placing each file on your local machine but with only the selected files and folders being physically present on your drive,
+the others are replaced by symbolic links pointing to a directory that is mounted from your server.
+
+See this 
+:ref:`example_how_it_works`.
