Clean up spaces
+ upcase.rb to convert :lowercase table to :uppercase table

Using this util we only need to handle a smaller table (~1100 entries).

There is still problem. Some words in form "Uppercase" is not valid,
for example "owix" will not be displayed as "Owix". We accept this!!!
upcase will  print 3 forms of an entry

If the input line is "abc => xyz", the output would be three lines
  abc => xyz
  Abc => Xyz
  ABC => XYZ
