invisible(TRUE/FALSE) - was the installation successful or
not. (this is based on the output of shell of running the
command being either 0 or 1/2.  0 means the file was
succesfully installed, while 1 or 2 means there was a
failure in running the installer.)

\description{
Gets a character with a link to an installer file,
downloads it, runs it, and then erases it.
}
\details{
This function is used by many functions in the installr
package. The .exe file is downloaded into a temporary
directory, where it is erased after installation has
started (by default - though this can be changed)
