want to using multiple contract block

[KimHunJin]

Hello. I'm mos, student developer in Korea.

First, Thanks for crate this library.

However, We needs using multiple Contract block.
for example

Contract A {

}

Contract B {

}

Currently, I can make just one Contract block.

Where should I fix it?

Thanks.

haha,, I solve it.

Exception handling is required, but can create multiple Contract blocks.
