Branching to try out statistical cut-offs

I am going to try and use mean plus/minus SD or standard error of the
mean to see if I can include the row, instead of highest values minus
10%.
Completed the function

Completed the function.  It will check if the values are within mean
plus/minus one standard error of the mean.  This can be skewed by
outliers.  This will need extensive testing.
we need to ignore some file

I do not want the vim temporary files to be committed.
removed the vim temporary file.
Update .gitignore
Updating simple_filter.R

Made changes to the editor o that the white space at the end of lines
is stripped.
Using the newly minted function to filter the data.  This needs testing.
Trouble shooting

Debugging the filter based on statistical values.
Hopefully this will fix one error.
Previous edit at wrong place.  This is fix the error.
Fixed typo.
Increasing the threshold.
We will try standard deviation instead of standard error of the mean.
This should widen the window of acceptance.
