> There are two important Source IO's that allow for dealing with text files 
> FileIO and TextIO. When the requirements go beyond the scope of TextIO we ask 
> the end user to make use of FileIO and go it on their own.
> We want to correct this experience by creating a more feature rich TextIO 
> which can return along with each line of data contextual information about 
> the line. For example the file that it came from, and the ordinal position of 
> the line within the file.
> Another area that we would like to deal with is more formal support for CSV 
> files by allowing compliance to RFC4180 files. Specifically the RFC allows 
> for line breaks (CRLF) to be used within fields within double quotes.
