Update GS6013 Getting Started With Macros

Hi all,

I finished to make changes to GS6013. To the greater extent this is an
attempt to clarify terms that may not be clear to a novice and the
replacement of some screenshots. The document has a record of changes and
comments, so I hope what reasons why I make that changes, and it will be
clear.
