eveything that happen

-initialisation-> calibration
-dellivrer/recuperer-> aspiration/injection
-worn diameter-> screw pitch

Add the length syringe pump modification available

-Put back the update slider function (which des not work neither)

-Update the value of the syringe chosen( does not completely work)

-Initialize internal_diameter_mm_new_syringe_value and
total_volume_mL_new_syringe_value so when we don't change them they
still exist to their initia value (which is 5)

Now that the first draft of the graphical interface has been completed, it's time to link the syringe and engine code to it.

Fxing problem in initialisation (it was moving and not initialising  and changing visibility true/false to enability (for the button initialisation) so it cannot be used when we don't want it to) (Imust now change the colors in that case by creating a ne style)

Fixing arduinoson problems by using singletons for syringe and syringefilled instead of static members.
