====== Perl Project - Retrieve Web Advisor Course Timetable ======

Due: Tuesday, Feb 26, 2019, 11:59pm

Work in groups of 2-3.

Write a Perl script, //**wa_timetable.pl**//, to retrieve a department course timetable from https://www2.monmouth.edu/muwebadv/wa3/search/SearchClassesV2.aspx.

//wa_timetable.pl// will take the following command line arguments:

<code>
  * Term          : which Term (semester) the class is in, e.g. "19/SP - Spring 2019"
  * Subject       : which Subject the class is in, e.g. English
  * -help        : display a help screen and sample usage
  * -terms       : list all currently available Terms
  * -subjects    : list all currently available Subjects
</code>

A sample usage for //wa_timetable.pl// is:

<code>
      perl -w wa_timetable.pl "19/SP - Spring 2019" "English"
</code>

The above run of //wa_timetable.pl// must return **the html document** that displays the course timetable for English, Spring 2019.

For the //-terms// and //-subjects// command line arguments, //wa_timetable.pl// must extract and display currently available Terms and Subjects from https://www2.monmouth.edu/muwebadv/wa3/search/SearchClassesV2.aspx.

===== Outline of possible approach: =====

  * Use a Perl web interaction module to retrieve https://www2.monmouth.edu/muwebadv/wa3/search/SearchClassesV2.aspx into a variable.
    * From that variable, extract the available Terms and Subjects into arrays.
      * The technique used at http://perldoc.perl.org/perlrequick.html#Extracting-matches and in [[perl_exercises#exercise_7_-_extract_data_from_html|Perl exercise 7]] is recommended.
