This module is used to read data from text based files. It supports multiple file formats. The module can be used to read data from a single text file or from a series of text files that are date stamped (e.g data.20080101.txt, data20080102.txt, etc.). To read a series of text files that are date stamped, define the file directory, file prefix (e.g. data.), date range, frequency and format (e.g. yyyyMMdd) and file suffix (e.g. .txt).
