`filename`	A character string for the name of the text file to be imported
`fun`	An R function that is going to be used to read the file. Default to `read.table`
`file`	A character string for the name of the argument to fun that defines the name of the file to be read
`basic`	A vector of character strings for names of the arguments to fun that will have separate entry boxes on the widget to be produced. Default to "header" and "sep"

This function is only partially finished and will be improved soon. It currently allows uesrs to view a given file and change the settings for header and sep arguments of read.table. A file will be read in based on the values of the two arguments and return.

This function returns a data frame for the file read in.
