Be able to exclude a file from results

Add the ability to exclude a particular selected set of files/directories from the current analysis. So after showing results (say, Top 100), I could select a set of files or directories from those results, right click them and choose "Exclude from This Analysis", and the analysis would be re-run excluding the selected files/directories.

For example, if one file is way bigger than all the others, I could exclude it and see results for just the similarly sized files.
