Detailed Description

class for reading txt files

first line has to give the names of the variables, which are then ordered line by line.

User definable Parameters:

TxtReader/%filename%/{Deliminator}
The deliminator that is used to separate the values. Default is '\t', which is a tab.

TxtReader/%filename%/{EventIdHeader}
The name of the Header under which the Event Id is stored. Default is "".

TxtReader/%filename%/{LinesToSkip}
How many lines do we have to skip before the line appears that contains the headers. Default is 3
