Added better pointer declaration readability (#567)

Browse source 
* Add better pointer declaration readability

I revised the declaration of single-line pointers by splitting it into
multiple lines. Now, every pointer is declared (and initialized
accordingly) on its own line. This refactoring should enhance
readability and decrease the probability of error when a new pointer is
added/removed or a current one has its initialization value modified.

* Remove unnecessary whitespace characters and lines

It removes whitespace characters at the end of lines (empty or
othwerwise) and clear lines at the end of the file (only one remains).
It is an automatic operation done by git.
