Instructions to build the examples

[bibhas2]

Please add instructions in README.md on how to build the examples. I ran cargo build from the root folder of the project but the examples didn't seem to get created.

You need to include the optional --example parameter with the name of the example to build. This is a standard feature of Cargo. For instance, to build and run basic.rs:

cargo run --example basic
