* --format "table {{.field..." will print fields out in a table with
headings. Table keyword is removed, spaces between fields are
converted to tabs
* Update parse.MatchesJSONFormat()'s regex to be more inclusive
* Add report.Headers(), obtain all the field names to be used as
column headers, a map of field name to column headers may be provided
to override the field names
* Update several commands to use new functions
