**What it does** 

This tool creates a text file with recurring lines. You can specify a bunch of characters or entire sentences. 
The entire string will be printed X times separated by a line break. X can be either given by the use as a number or calculated by a given file.
In case the user provides a file, the line number will be used as X.
