identify_date_string.cpp

/* identify_date_string.cpp
 
reads from, line by line, a text file: INPUT.txt
adds a newline when it encounters a comma
removes commas and quotes from a CSV file
writes to, line by line, a temporary output text 
file: DUDE_tmp.txt

then identifies the specific date objects in the
input text file and replaces them with the string
"DATE"

the next step in the program will be to add a date
manip object
