1.  Works with the revised Pew Research Center website, which
    necessitated a switch back to RSelenium from rvest.
2.  By default, automatically converts downloaded datafiles to .RData
    format.

                 Changes in version 0.2.0 (2016-09-24)                  

1.  Faster
      - Revised the function to be more compact with the rvest
        functions.
      - Replaced the if-else if chains with the switch statements.
      - Overwrote the for loop by a sapply function.
2.  More user-friendly
      - Users do not need to set up the .Rprofile by themselves. If the
        information is missing the function will automatically call an
        input request at the terminal to ask for required information
        for the downloading.
      - Users can reset the register information stored in the .Rprofile
        by switching the argument reset to TRUE.
      - The function no longer relies on the Firefox browser.
