Version 0.3.0

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.

Version 0.2.0

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.
