Create rule DDF00025: If a Timing is of type "Fixed reference" then window, windowLower, and windowUpper are all null.

[ASL-rmarshall]

Create rule defined for #118

[ASL-rmarshall]

Changed DDF99987 to DDF00025. The rule reports an error if any of window, windowLower or windowUpper is non-empty and either type.code is "C201558" or type.decode is "Fixed Reference" (ignoring text case). This is ready for review.

Negative test data returned 3 errors, as expected. Positive data returned no errors.
