Make display of timer optional i.e. configurable upon startup

[maxradx]

Indeed, I would remove any timer display in the module and make segmentation time of each segment (as currently done) automated. Rationale: the user should not see any timer while performing annotation since this can cause Hawthorne effect (bias)

Specifications

• add a new configuration (like "display_timer_requested") in general_config.yml
• add a new checkbox or combobox in the class SlicerCARTConfigurationSetupWindow for this
• set the visibility of the timer to follow the value of this new configuration

  self.ui.lcdNumber.setVisible(bool_value)

Note : take another parameter as an example like is_keyboard_shortcuts_requested.

Expected behaviour If the configuration value is False, the timer should not be visible to the user. If the configuration value is True, the timer should be visible to the user. In both cases, the duration is written to the *SegmentationInformation.csv file. It is a useful metric that should be kept.

should we still use start/pause/restart buttons for the case where the configuration value is False? If not, what would be the cue to start the timer in the background?

[delphinepilon]

I like the idea of keeping the start / pause / restart buttons. It gives the user the opportunity to temporarily stop the timer in the middle of an annotation. Otherwise, the duration of the annotation could be less accurate. I don't know what others think?
