Berthold Stoeger 5c248d91cd Coding-style: remove superfluous parentheses 
Mostly replace "return (expression);" by "return expression;" and one
case of "function((parameter))" by "function(parameter)".

* An .slg file is composed of a main table (Dives), a bunch of tables directly

* independent tables (Activity, Type, Gear, Fish ...) which connect with the dives
* via a related group of tables (ActivityRelation, TypeRelation ...) that contain
* just the dive index number and the related table index number.
* The data stored in the main group of tables are very extensive, going far beyond
* the actual scope of Subsurface in most of cases; e.g. Dives table keeps
* information which can be directly uploaded to DAN's database of dives, or Buddy
* table can include telephones, photo or, even, buddy mother's maiden name.
*
* Although these funcs are suposed to work in a standalone tool, will also work
* on main Subsurface import menu, by simply tweaking file.c and main_window.cpp
* to call smartrak_import()
