/**
* Class to represent an error raised due failure in Scrivo program logic.
*
* This class is for runtime errors of a technical nature that should normaly
* not occur in script execution, with script termination as most the likely
* course of action. For instance:
*
* * Division by zero where there was no user input.
* * Illegal argument types.
* * Index out of bounds.
*
* You can use these errors to discriminate between resource exceptions,
* system exceptions and application exceptions to take appropriate
* action: f.i. notify the system admin, send out bug report or prompt the
* user for new input.
