public static Range getStringRange(String str) {
        return new Range(new Position(0, 0), getStringPosition(str));
    }
Indents all lines of a string except the first one by indentDelta spaces. If indentDelta is negative it will unindent.
Similar to selecting a block of text and hitting tab/shift-tab (or &lt;, &gt; in vim), but not quite equal. If you try to unindent by more spaces 
than the current indent of a line, nothing will happen.

@param text the text to modify
@param indentDelta number of spaces to add or subtract indentation.
@return the modified text
