[Lazarus] CSV parser class

[Juha Manninen]

Hi,

I think there is need for an OPTIMIZED code for splitting and joining.
TStringList.DelimitedText is good when speed is not very important.
See:

I didn't look at tiOPF project's implementation so I don't know how optimized 
it is.

"CSV" is little misleading because the separator can be some other than comma. 
Text itself often has commas and thus the text between separators must be 
quoted. TAB is a much better separator because it seldom occurs in text.

Splitting can be slow. It creates and copies strings and allocates small 
chunks of memory.
There should be variations for those functions. Sometimes you want to support 
quoted stings, sometimes not.
Sometimes you want TStrings, sometimes an array of string (which allows more 
optimization).
