This check replaces default bodies of special member functions with
= default;. The explicitly defaulted function declarations enable more
opportunities in optimization, because the compiler might treat
explicitly defaulted functions as trivial.
Additionally, the C++11 use of = default more clearly expreses the
intent for the special member functions.

Converts a default constructor’s member initializers into the new
default member initializers in C++11. Other member initializers that match the
default member initializer are removed. This can reduce repeated code or allow
use of ‘= default’.

With move semantics added to the language and the standard library updated with
move constructors added for many types it is now interesting to take an
argument directly by value, instead of by const-reference, and then copy. This
check allows the compiler to take care of choosing the best way to construct
the copy.
The transformation is usually beneficial when the calling code passes an rvalue
and assumes the move construction is a cheap operation. This short example
illustrates how the construction of the value happens:

This check is responsible for using the auto type specifier for variable
declarations to improve code readability and maintainability.
The auto type specifier will only be introduced in situations where the
variable type matches the type of the initializer expression. In other words
auto should deduce the same type that was originally spelled in the source

The emptiness of a container should be checked using the empty() method
instead of the size() method. It is not guaranteed that size() is a
constant-time function, and it is generally more efficient and also
shows clearer intent to use empty(). Furthermore some containers may
implement the empty() method but not implement the size() method. Using
empty() whenever possible makes it easier to switch to another container
in the future.

The check converts the usage of null pointer constants (eg. NULL, 0) to
use the new C++11 nullptr keyword.

* Added setting precision for writers.
* Added special case for precise precision and global precision.
* Added good setting of type of precision and also added this type to BuiltStreamWriter and for its settings.
* Added some tests.
`valueToString` takes an argument `unsigned int precision`, but it is used with `%d` rather than `%u` in the `snprintf` format string. Make the format string look for an unsigned value instead.
The output of snprintf might produce ',' separators for decimal places if
certain locales are set. This commit moves the converversion from ',' to '.'
to correct place. Otherwise an additional ".0" might be appended.
