Added a "how to read file" example

[MattBrou]

Took me a while to figure out how to properly read a file with SMBJ library. So I thought I'd share my solution.

Yes, I agree with to add a example on how to read & write file.

As documentation did not mentioned about it.

@MattBrou,

Do you have an example on how to write new content into file after read a file?

Flow:
Read File -> Add New Content -> Write File -> Save File

You should also nest the share.openFile in a try-block, as the File object needs a close to release.
And don't forget to properly close the smbFileRead.getInputStream()
