Title: Switch DelimitedParser to a hybrid regex/CSV parser implementation 

Splitting using just a delimiter as the regex is very fast, even faster than using opencsv. In the new DelimitedParser, it will continue to use the regex approach when a quoting character has not been defined. When the user does define one, it will switch to using opencsv to parse each line.
