Added scripts to measure the length of rectangle ROIs

[willsides]

Added two scripts to measure the short or long dimension of a rectangle or rotated rectangle ROI. The other dimension of the rectangle is used to draw extension lines. Also tweaked choose_microscope_calibration.py to make language of the 'global scale' checkbox more accurate.

Thanks for your contribution @wdsides !

I tried running this and am getting the error:

[ERROR] Traceback (most recent call last):
  File "Analyze/Microscope Measurement Tools/Choose_Microscope_Calibration.py", line 42, in <module>
ImportError: No module named Microscope_Calibrations_user_settings

I downloaded directly from your repo, unzipped and moved into my FIJI folder in:
/Applications/Fiji.app/plugins/Scripts/Analyze/Microscope Measurement Tools/

But it keeps giving this error. Do you know if there is a bug somewhere? Files appeared to be named correctly, I didn't look further into the code yet.

So sorry I haven't gotten around to responding until now. I did have a reason to revisit this today and made some changes to the readme to explain the new features and update the install instructions.

I think that error is related to your directory structure. The repository is structured to be copied directly into the directory Fiji.app/ which will then add the folder /Fiji.app/plugins/Analyze/Microscope Measurement Tools/ as well as overwrite the file /Fiji.app/macros/StartupMacros.fiji.ijm (this adds the toolbar icons and hotkeys - I'm not aware of a way to do this without overwriting this file).

@willsides i don’t see how copying the Analyze folder can overwrite that startup script file.
the instructions say to manually “merge” the folder structure - perhaps that is too complex an ask?

[demisjohn]

Oh are you saying I also need to copy the startup scripts file, not just the Analysis folder?
