Eclipse metadata, Emacs *~ and .pyc are now ignored.

Tested functions:
	* findStaffLinesInImage()
Tested classes:
	* VideoFrameWriter:
		- image handling methods:
			. isLineBlank()
        		. getTopAndBottomMarginSizes()
			. getCropTopAndBottom()
			. cropFrame()
		- time handling methods:
			. ticksToSecs()
			. secsElapsedForTempoChanges()

To maintain the code more easily, the program will be split into several modules.
setDebug() and setRunDir() functions are handling global var DEBUG and runDir.

Move VideoFrameWriter and some image scanning functions into a new 'video' module.
Update unit tests.

Avoid an 'undefined var' at execution?

…avelling

Some VideoFrameWriter methods are now moved to this class.
The getCropTopAndBottomMarginSizes() method is replaced by the topCroppable() and
bottomCroppable() methods which respectivly return the number of pixels the image can
be cropped on top an bottom.
An instance is now used by VideoFrameWriter.

Some unused code has been removed in VideoFrameWriter (write and secsElapsedForTempoChanges)

Update the tests for the new class ScoreImage.
The tests of image handling methods are moved to the ScoreImageTest test class.

Tested functions:
	* findStaffLinesInImage()
Tested classes:
    	* VideoFrameWriter:
    		. ticksToSecs()
    		. secsElapsedForTempoChanges()
	* ScoreImage
    		. __isLineBlank()
    		. __setCropTopAndBottom()
    		. __cropFrame()
		. topCroppable()
		. bottomCroppable()
		. makeFrame()

...instead of image notes indexes.
Less dependant from the scoreImage class.

The ScoreImage instance of VideoFrameWriter can now be set as a public property.
Some parameters of the VideoFrameWriter constructor are removed and the
write() method has now no parameter. These parameters are attached to
the ScoreImage instance.

Implements a measure cursor that is slightly less intrusive than the line
cursor following each note.
Updates writeSpaceTimeDumper() function the measures bars positions.
New function getMeasuresIndices().

These options are added to be more coherent with --measure-cursor, and to allow no cursor at all.

… video

VideoFrameWriter is now able to push up medias.

This cursor can be used when the slide show displays some structure diagram.
Some hard coded values should be set by command line options...

…ns of the cursor

Deletes height and width in VideoFrameWriter constructor
(No height limit, score)

Tested classes:
	* VideoFrameWriter:
    		. push()
    		. scoreImageSetter()

…he video

Time handling methods are moved to this class.
The design pattern 'Observer' is used.
New 'synchro' module.

Add tests for the new class TimeCode, update some tests.
Some new fonctional tests (testCompleteFollowing)

Tested classes:
	* TimeCode:
		. ticksToSecs()
		. secsElapsedForTempoChanges()
		. nbFramesToNextNote()
		. goToNextNote()
		. atEnd()
	* ScoreImage:
		. currentXposition
		. moveToNextNote()
		. cropFrame()

As of Python 2.7, optparse is deprecated in favour of argparse.
