Create a command line tool that determines the average sentence length of a text file.
- No Special Libraries (Vanilla Python 3)
- Script should run from command line without any special options
- User specifies the file path of a .txt ** If the user enters an invalid file path the user should be asked for the file path again.
- User specifies delimiters (sentence separators)
- User specifies the minimum word length limit
- The program should output the average sentence length rounded down to the nearest integer.
