Checks that all exceptions thrown by function are properly documented in it's PHPDoc with @throws tags.

Options:

• Analyze immediate calls: if the option is on, the inspection will also check called functions for exceptions they may throw. It checks only the exceptions directly thrown by these functions ignoring nested function calls.
• Ignore Runtime exceptions: tells not to report undocumented runtime exceptions (either base RuntimeException or any of its subclasses).
  
• Ignore Logic exceptions: tells not to report undocumented logic exceptions (either base LogicException or any of its subclasses).
  

Note: if "Ignore Runtime/Logic exception" option is off, @throws tags for runtime/logic exceptions are also automatically added upon PhpDoc creation/update.
