Adding a Band-pass filter (#44)

* Added bandpass filter function place holder.

* added a bandpass filter. Function is written in gprpyTools and then it is called from gprpy module. I mimicked the existing strucutre and the undo function appears to work. Need to add some more documentation. I converted self.data into an array (from a matrix) to do the calcuation and then make sure is a matrix being passed back.

* Added a plot spectrum funciton, mainly to verify the band pass filter

* Added descriptions to the functions

* Added a band-pass button. It is not funcitonal yet. I coppied the format from Alain's other buttons

* Added the functionality to the band-pass button. I really wanted to plot the spectrum to confirm that it was working. I don't know how to get it to pop up a new window though. This is becasue I think that I have to place the plot onto a TK canvs??. It is also unclear if the undu button is working, but it does write the script properly

* removed wrong/old test function
