Text improvement on clients documentation

[tsolakoua]

In the clients guide:

The client API's differ to adapt to their language specific idioms, the following [codes] [shows] several simple examples with the Go, Python and Scala clients that [parsers] a file and [applies] a filter to return all the simple identifiers.

• I don't know if it's correct in english using the plural codes. Maybe it could be replaced with code snippets for example.
• shows should be show also.
• parsers -> parse
• applies -> apply

As I'm not native english speaker, every time I mention something non-trivial please double-check if possible in case I am wrong.
