Can Message Settings
************************

| One of the key features of the application is the ability to set the CAN specification for individual variables.
| The list of all variables is in the case of dashboard displayed on the right side of the application.
| In case of other views, only those variables that occur in that view are listed.

| The user can open a settings window for any variable.
| This is done either by selecting one of the variables and then clicking on update button or by double-clicking on any of them.
