   * Given a subject area and course number, return a course id that is formatted similarly to the
11 
   * precise way that course numbers are formatted in UCSB's GOLD system.
12 
   *
13 
   * <p>That format has the subject area left justified in an 8 character field, followed by the
14 
   * course number right justified in a 3 character field, followed by the suffix (if any) left
15 
   * justified in a 2 character field.
16 
   *
17 
   * <p>However, we use this function to query rtora's CSV files with grade data, at
18 
   * https://github.com/rtora/UCSB_Grades/ in which this course id is trimmed, such that there are
19 
   * never ending spaces.
20 
   *
21 
   * <p>Therefore, we intentionally also trim the result course id in this function to properly
22 
   * query the CSV files. For example, CMPSC 130A would typically be written:
23 
   *
24 
   * <p>"CMPSC 130A "
25 
   *
26 
   * <p>but we return "CMPSC 130A" to query the CSV file.

   *
28 
   * @param subjectArea subject area, such as CMPSC
29 
   * @param courseNumber course number, such as 130A
30 
   * @return formatted course number
