Implemented automatic SR-EELS detection and the EFTEMjLogTool.

I used the existing SR-EELS correction and added it to EFTEMj. I have
done only a few changes. The next step is to add the manual detection.

EFTEMjLogTool is a small program to save a process log and show it at a
GenerigDialog. This is only a draft that needs to be extended.
Added the manual detection mode.

As for the automatic detection mode I only copied the existing code.
Some modification were necessary to be able to run the method.

It is necessary to clean up the code.
Added the SR-EELS correction (I reused the existing code).

This code needs to be enhanced. I have to add a method (e.g.
doCorrection()) that can be called from SR_EELS_CorrectionPlugin.
Extended EFTEMjLogTool.

To write log messages an instance of EFTEMjLogTool has to be created.
All messages are written to a local and a global message-buffer. The
global message-buffer is not jet used.
Modified SR_EELS_CorrectionPlugin and SR_EELS_CorrectionOnlyPlugin.

SR_EELS_CorrectionPlugin calls SR_EELS_CorrectionOnlyPlugin for final
processing. SR_EELS_CorrectionOnlyPlugin has to be modified for this
purpose.

SR_EELS_CorrectionOnlyPlugin: I added all necessary comments.

SR_EELS_CorrectionPlugin: I optimised the manual mode.
I enhanced SR_EELS_CorrectionPlugin.

The goal of the enhancement was to optimise the automatic detection. The
code is much more compact now and the optimisation of maxCount is much
more integrated by using a do-while-loop.
Worked on SR_EELS_CorrectionPlugin & SR_EELS_CorrectionOnlyPlugin:

SR_EELS_CorrectionPlugin:
1. Start SR_EELS_CorrectionOnlyPlugin by using IJ.run("Command").
2. Added code to determine the default values of parameters.

SR_EELS_CorrectionOnlyPlugin:
1. Included two methods into correctData().
2. Optimised the calculation of newSpecWidth.
SR-EELS correction has been completed:

1. Both detection modes are fully implemented.
2. Only a few comments and the text for the help dialog are missing
3. The correction plugin is started at the final processing of the
detection plugin (see
