Need a way to extract parsed headers, e.g. for use in formatting output
-----------------------------------------------------------------------
Key: IO-317
URL: https://issues.apache.org/jira/browse/IO-317
Project: Commons IO
Issue Type: New Feature
Reporter: Sebb
Parsed header names are currently not accessible except as field key names, but
these have to be known in advance.
It would be useful to be able to have access to the header names:
* to use in printing a header for a new CSV file. E.g. to read a CSV file and
produce a new one with some changes made.
* to write generic CSV applications
The headers could be made available as a String array (in column number order)
from the CSVParser class.
The simplest would be to store the parsed (or provided) headers and return a
clone of the array.
If headers were not provided or requested, the method should probably return
null rather than an empty array - to be decided.
