Support for arrays nested in other array.

[seban]

When I have need to use nested arrays in savon SOAP client, but this is case caused bug in my opinion.

irb(main):001:0> Gyoku::Array.to_xml([[{ value: "1" }]], "Map")
=> "<Map>[{:value=>\"1\"}]</Map>"

Nested array is treated with to_s method. IMO it could be treated as normal Array. I done some workaround in https://github.com/seban/gyoku/commit/e7706cfaea69bba655d30c49c1eabe6893bddc3d. After my fix it looks like:

2.0.0p247 :001 > Gyoku::Array.to_xml([[{ value: "1" }]], "Map")
 => "<Map><element><value>1</value></element></Map>"

If it is ok for you I can submit pull request.

@seban thanks for opening this issue. A pull request would be lovely! Do you think it would be possible to write some tests for this behavior?

[seban]

@tjarratt I added tests to array_spec.rb isn't it enough?

[tjarratt]

Oh, I'm sorry. I hadn't noticed the linked commit in your first comment. That looks great!

Would you please issue a PR so we can get it merged in?

[tjarratt]

@seban I'll bump a new version of Gyoku later today and push it out to rubygems.org. In the meantime, I'm going to keep this issue open to remind myself to do that.

Just released version 1.1.1 with this change. Please let me know if you find any other problems @seban -- there were a few other changes since 1.1.0 was released in July.
