Subject: [PATCH] Minor fixes to C++ Smart Pointer section

* Fix minor spelling / grammar problems ("tp de-allocate", "refences", "dont"...)
* Remove filler words ("Basically", "As a matter of fact"...)
* Remove spaces before parens in smart pointer initialization code sample (consistent with the other sections, e.g. the `Tuples` section)
* Clarify `std::weak_ptr` use case

-// As mentioned before there is a set of smart pointers. The way you have to
-// use it, is always the same.
-// This leads us to question, when to use which one?
-// std::unique_ptr - use it when you just want to hold one reference on
-// the same object.
-// std::shared_ptr - use it when you want to hold multiple references on the
-// same object and want to make sure that it´s de-allocated
-// when all refences are gone.
-// std::weak_ptr - use it when you want to hold multiple references from
-// different places for references for which it´s no problem
-// tp de-allocate.
+// There are several kinds of smart pointers. 
+// The way you have to use them is always the same.
+// This leads us to the question: when should we use each kind of smart pointer?
+// std::unique_ptr - use it when you just want to hold one reference to
+// the object.
+// std::shared_ptr - use it when you want to hold multiple references to the
+// same object and want to make sure that it's deallocated
+// when all references are gone.
+// std::weak_ptr - use it when you want to access
+// the underlying object of a std::shared_ptr without causing that object to stay allocated.
+// Weak pointers are used to prevent circular referencing.
