Refactor and update model element colors
Allow to modify double values using the EFSDriver
Allow to display external events as actions in the time line (the same as the actions located in a step)
Model element location update
Added the braking curves verification in the nightbuild
Release 1.0.21
Added state transitions to the state machine, some automatic changes happened, too
EA_MODEL Removed redundant type (TargetsCol, collection of Kernel.SpeedandDistanceMonitoring.Target)
EA_MODEL Implementation of 3.13.10.6 Transitions between types of speed and distance monitoring
Use version 2.29.2 of XMLBooster
EA_MODEL Started fixing tests (16 tests fail)
Provide the right display information for ModelInterpretationFailure
Provide an explanation for a model interpretation failure
EA_MODEL Modified calculation of deceleration curves (20 tests fail)

Compute the explanation when an interpretation failure occurs
Merge branch 'Upstream/master'
Added explain view for "Cannot evaluate function" error
EA_MODEL Corrected Compute_d_PreIndication pre conditions
Can make special values of enums forbidden for arithmetic, DistanceForSpeed returns "Unknown" in cases where it returned no value previously
