       "LaTeXML::Common::Locator" contains a reference to a point or range within a source file.  This data
       structure is intended to be used both programtically (for "source references") and to display error
       messages to the user.

       It extends LaTeXML::Common::Object.

   LocatorCreation
       "$locator = LaTeXML::Common::Locator->new($source, $fromLine, $fromCol, $toLine, $toCol);"
           Creates  a  new  locator.  $source should be a string containing the full path of the source file, an
           empty string in case of a literal string, or undef in case of  an  anonymous  string.  $fromLine  and
           $fromCol  should  be integers containing the line and column numbers of the start of the range in the
           source file, or undef if unknown. $toLine and $toCol should be the integers containing the  line  and
           column numbers of the end of the range, or undef if a point is being referred to.

       "$locator = LaTeXML::Common::Locator->newRange($from, $to);"
           Creates  a  new  locator, starting at the locator $from and ending at the locator $to. Either locator
           may be undef, in which case the other one is returned.

   Methods
       "$str = $locator->toString;"
           Turns this locator into a short string for output in user messages.

       "$str = $locator->stringify;"
           Turns this locator into a long string, including the full filename of the input.

       "$attr = $locator->toAttribute;"
           Turns this locator into an XPointer expression, for usage within an XML attribute.

       "$isRange = $locator->isRange;"
           Checks if this locator points to a range or a point.

       "$source = $locator->getShortSource($stringSource);"
           Gets a short string referring to the source of this locator.   $stringSource  will  be  used  if  the
           source refers to an anonymous or literal string input.

       "$from = $locator->getFromLocator;"
           Gets  a  locator  pointing to the first point in the range of this locator.  Works for both point and
           range locators.

       "$from = $locator->getToLocator;"
           Gets a locator pointing to the last point in the range of this locator.   Does  not  work  for  point
           locators.
