Code generation: unit scaling for rate computation is the other way round

[agarny]

Say that the VOI is defined in seconds in a component called environment and that a state , x expressed in metres, has its rate computed in a component called main using the VOI expressed in milliseconds. Right now, our code generator would generate something like:

rate[0] = 0.001*...;

while it should generate something like:

rate[0] = 1000.0*...;

Indeed, the rate of x in main is expressed in metres per milliseconds, but to compute the model we need it to be expressed in metres per seconds, hence we need to multiply the calculation of the rate of x by 1000.0 and not by 0.001.

To multiply by 0.001 would be needed if x had been expressed in kiloseconds (!!).
