In the tool vitrinite the button "get tie point" doesn't work!

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open vitrinite tool
2. Open marker image
3. Get tie point

What is the expected output? What do you see instead?

I'll should select several tie points to calibrate my sample image. Instead of 
that I hear an error noise and is impossible to get a tie point.

What version of the product are you using? On what operating system?
Mirone 2.2.0, matlab 7.12.0.635(R2011a), Mac OS X Lion 10.7.

Please provide any additional information below.

This tool is rather poorly documented, I know (the colleague that asked me to 
write it should have worked more on that). 
You will need at least 2 marker images (but the more, the best) that are named 
with the following convention

xxxx_numericReflectance.ext

Here is an example name that I use:

Padrao_1.715.jpg

the reflectance of the marker image is extracted from the file name. After 
having loaded you marker images, you click the "Get tie point" button and click 
on the marker image only once. You do this for each of the marker images.
Next you do "Calibrate" and finally you can use the "Get average reflectance" 
on the sample image that you have loaded meanwhile.

I added a couple more tests to vitrinite tool to prevent doing some usage 
errors and updated the SVN version.
