   Purpose:
        To remove preceding and trailing blanks from a string

   Strategy:
        1. On calling:
        2. work from front of string - find first nonblank
        3. work from end of string   - find last nonblanks
        4. return middle bit

   Input:
        fromThis = string to be stripped

   Output:
        fromThis = stripped string

   Examples:
        1. fromThis = "  January " returns fromThis = "January"
