// A utility function that adds a preamble to each Netscript JS
// script. This preamble will set all the global functions and
// variables appropriately for the module.
//
// One caveat is that we don't allow the variables in the preable
// to change. Unlike in normal Javascript, this would not change
// properties of self. It would instead just change the variable
// within the given module -- not good! Users should not really
// need to do this anyway.
