Branch info

There are two branches in this repo - main and multi. main branch serves an example of two separate WASM modules like add and sub which can be debugged separately. multi branch serves an example of an host application which loads two WASM modules like add and sub from WAT and tests a simple application graph with two WASM modules connected sequentially. It also contains two .wasm files (add.wasm and sub.wasm) from add.rs and sub.rs which are not used currently
