change_type — modify the type of declared variables/parameters

Changes the types of the specified variables/parameters to another type: endogenous, exogenous, exogenous deterministic or parameter.
It is important to understand that this command has a global effect on the .mod
file: the type change is effective after, but also before, the change_type command. This command is typically used when flipping some variables for steady state calibration: typically a separate model file is used for calibration, which includes the list of variable declarations with the macro-processor, and flips some variable.
