Detailed Description

Parses a delimited text file (e.g.

a CSV or tab-delimited file), and emits signals that represent data series from the file.

To use it, create an instance of pqDelimitedTextParser, passing the delimiter character in the constructor. Then, connect the startParsing(), parseSeries(), and finishParsing() signals to slots. Call parse() with the filename of the file to be parsed, and the parseSeries() signal will be emitted for each series of values contained within the file.
