Options for ctags

[armijnhemel]

When pretty printing to JSON with universal ctags the following fields are printed by default (see man page for ctags what stuff means):

• name
• path
• pattern
• file
• typeref
• kind
• scope
• scopeKind

It might be good to figure out which fields are useful. It could very well be that some files are not very useful, while others are missing. Some that I think might be good to include (with the --fields parameter):

• line (line number information)
• access

although there can be others, depending on the language. I am not sure if all the default tags should be included.
