vPhraseOne: First of two phrases which are to be compared to determine their similarity. Function returns Null if vPhraseOne is Null or cannot be fixed up to a String.

Note: Strings are first converted to upper-case so that, in effect, this function uses Text comparisons to determine if characters match.

vPhraseTwo: Second of two phrases which are to be compared to determine their similarity. Function returns Null if vPhraseTwo is Null or cannot be fixed up to a String.
