Detailed Description

   template<typename _CharT, typename _Traits, typename _Alloc>class std::basic_string< _CharT,
       _Traits, _Alloc >
       Managing sequences of characters and character-like objects.

       Meets the requirements of a container, a reversible container, and a sequence. Of the
       optional sequence requirements, only push_back, at, and array access are supported.

           for more.

       Documentation? What's that? Nathan Myers <ncm@cantrip.org>.

       A string looks like this:

                                               [_Rep]
                                               _M_length
          [basic_string<char_type>]            _M_capacity
          _M_dataplus                          _M_refcount
          _M_p ---------------->               unnamed array of char_type

       Where the _M_p points to the first character in the string, and you cast it to a pointer-
       to-_Rep and subtract 1 to get a pointer to the header.

       This approach has the enormous advantage that a string object requires only one
       allocation. All the ugliness is confined within a single pair of inline functions, which
       each compile to a single add instruction: _Rep::_M_data(), and string::_M_rep(); and the
       allocation function which gets a block of raw bytes and with room enough and constructs a
       _Rep object at the front.

       The reason you want _M_data pointing to the character array and not the _Rep is so that
       the debugger can see the string contents. (Probably we should add a non-inline member to
       get the _Rep for the debugger to use, so users can check the actual string length.)

       Note that the _Rep object is a POD so that you can have a static empty string _Rep object
       already constructed before static constructors have run. The reference-count encoding is
       chosen so that a 0 indicates one reference, so you never try to destroy the empty-string
       _Rep object.

       All but the last paragraph is considered pretty conventional for a C++ string
       implementation.

       Replace range of characters with initializer_list. Parameters:
           i1 Iterator referencing start of range to replace.
           i2 Iterator referencing end of range to replace.
           l The initializer_list of characters to insert.

       Returns:
           Reference to this string.

       Exceptions:
           std::length_error If new length exceeds max_size().

       Removes the characters in the range [i1,i2). In place, characters in the range [k1,k2) are
       inserted. If the length of result exceeds max_size(), length_error is thrown. The value of
       the string doesn't change if an error is thrown.

   template<typename _CharT , typename _Traits , typename _Alloc > void std::basic_string<
       _CharT, _Traits, _Alloc >::reserve (size_type__res_arg = 0)
       Attempt to preallocate enough memory for specified number of characters. Parameters:
           res_arg Number of characters required.

       Exceptions:
           std::length_error If res_arg exceeds max_size().

       This function attempts to reserve enough memory for the string to hold the specified
       number of characters. If the number requested is more than max_size(), length_error is
       thrown.

       The advantage of this function is that if optimal code is a necessity and the user can
       determine the string length that will be required, the user can reserve the memory in
       advance, and thus prevent a possible reallocation of memory and copying of string data.

       Resizes the string to the specified number of characters. Parameters:
           n Number of characters the string should contain.
           c Character to fill any new elements.

       This function will resize the string to the specified number of characters. If the number
       is smaller than the string's current size the string is truncated, otherwise the string is
       extended and new elements are set to c.

       Resizes the string to the specified number of characters. Parameters:
           n Number of characters the string should contain.

       This function will resize the string to the specified length. If the new size is smaller
       than the string's current size the string is truncated, otherwise the string is extended
       and new characters are default-constructed. For basic types such as char, this means
       setting them to 0.
