sportdb Gem Guide Updated - Working w/ Football CSV Files - English Premier League 2019/20 - Let's Build the Standings Table

Hello,

   I've updated the hands-on getting started guide for the sportdb
text library / gem.

Let's build the standings table for the English Premier League (EPL)
for the 2019/20 season from all 40 matches (as of Sept/2) in the
comma-separated values (.csv) format.

In a nutshell:

require 'sportdb/text'

matches = CsvMatchReader.read( 'england/2010s/2019-20/eng.1.csv' )

standings = SportDb::Struct::Standings.new
standings.update( matches )

standings.to_a.each do |l|
  print '%2d. '     % l.rank
  print '%-28s  '   % l.team
  print '%2d '      % l.played
  print '%3d '      % l.won
  print '%3d '      % l.drawn
  print '%3d '      % l.lost
  print '%3d:%-3d ' % [l.goals_for,l.goals_against]
  print '%3d'       % l.pts
  print "\n"
end

resulting in:

 1. Liverpool FC                   4   4   0   0  12:3    12
 2. Manchester City FC             4   3   1   0  14:3    10
