Error Handling

[[toBeAdded]]
[[isInNewCommits]]

When you're writing a library or an utility in ISI, it would be
unconvenient to write errors as if statements with logging, custom error handling
and writing everything again.

That's why the 'throw' function WILL BE introduced in ISI [[isiVersionCommit:A3]]
Using the throw function is simple, you just do this:

int x = 8;
if (x < 128){
    throw("Variable x is smaller than 128", -1);
}

The throw function takes two arguments, but only the first one is required.
The first argument is a string, which is the message that gets printed
if the error won't be caught.
The second argument is an int, which is the error code that gets returned.
