This function makes it possible to directly access the data used in the gui
by starting a new R session and running this function. This will only work if
just one instance of MSGFgui is running in the browser. The data will linger
on so calling
currentData() when no instance of MSGFgui is running
will return the last set of data used.
An mzIDCollection object containing the current identification results in the the MSGFgui browser
results <- currentData()
