* Draft the integration of the Error Model in IMV
Delete some error messages
 * Update toolbar with appropriate actions & icons
Added figure for subprogram group component.

Still need to add fgiure for subprogram and subprogram group as feature.
* First implementation of the error model annex support
  for IMV
Fixed bandwidth budget analysis to handle connections other than port
connections (e.g., feature group connections).
It still considers budget attached to a feature group connection only
once even though it generates multiple port connections.
I.e., the property on teh feature group conneciton is not considered
inherited.
* Handle error for systems in IMV
* Handle connections going through different components
Remove useful variable
fixed issues with latency calculation. still had some confusion between
MS (MilliSec) and US (MicroSec).
Methods now reflect assumed unit.

Fixed units conversion for Binpacker.
conditionally print out a warning if budget is non-zero.
Updated to report using the new unit label for bandwidth.
Fixed SOM label in message when analyzing modal systems.
Change the background color of other figures in the AADL diagram

Added virtual processor support to resource budget analysis.
Added handling of viertual processor to scheduling.
