+"""
+Searches recursively all the modules from packages. As documentation grows, it's a bit
+troublesome to add all the new modules manually, so we've written with this function
+which searches all the modules automatically. 
+
+Parameters
+----------
+    module_: Module
+        Module where we want to search modules inside
+    append_list: Array{Module, 1}
+        Array, where we append Modules as we find them
+
+Returns
+-------
+    None. Void function, which manipulates the append_list
