Bug: Incorrect initial value for some Constant blocks in R2015a

If a MATLAB R2015a (or earlier) model contains a Constant block NOT within a conditional or triggered subsystem then the Constant's output value at t=0 and BEFORE the Constant block executes in Reactis is 0 instead of the constant value. Note that this only causes problems in very rare circumstances where blocks that depend on the Constant value execute BEFORE the Constant block itself.
