/**
* The Severity enumeration is used to determine the severity of an Issue.
* There are three levels/categories of severity:
* - SEVERE, for instances in which the issue has to be fixed, or the Dialogue will cause SDT to crash or otherwise experience uncaught exceptions;
* - MAJOR, for instances in which the Dialogue does not display as intended.
* Since the DialogueChecker does not have the ability to read the intention of the author of a dialogue, the DialogueChecker assumes that:
* All lines in a dialogue that are not commented out were meant to be played. (Unused lines are bad)
* All content in a line of a dialogue was meant to be displayed. (Failed substitutes are bad)
* All lines in a dialogue were meant to function correctly within SDT. (SDT should not fail to parse any lines)
* In the event that the application of these assumptions to a dialogue fails, the cause of the failure will be labeled an issue of MAJOR severity,
* unless the cause is already labelled as a SEVERE issue.
* - MINOR, for instances in which the issue does not entail an error or meets the requirements for SEVERE or MAJOR severity.
* Issues with a MINOR severity tend to entail grammatical mistakes, unnecessary sections of a dialogue or line, or syntactic styling of dialogue lines.
* These three levels can each be seen as MUST (Severe), SHOULD (Major) and COULD (Minor) - "be fixed".
* In case the DialogueChecker is unable to parse a dialogue or sections of a Dialogue, issues are automatically treated as SEVERE, due to the possibility of the affected sections to contain SEVERE issues.
