; This UDF "udfStrStrip" returns a substring from the given strString.
;
; Depending on whether parameter "intBoundary" is -1 (left edge), 1 (right edge) or 0 (both edges),
; the leading, trailing, or both leading and trailing occurrences of "strStripChars"
; will be deleted and the result string will be returned.
;
; Depending on whether parameter "blnMatchCase" is @TRUE or @FALSE,
; character casing will be respected or not.
