Default template set can not be used

[appleios]

My ruby is version ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14].

I've installed the gem with gem install generamba. Then as described here I did generamba setup and after answering several questions, I've got the Rambafile.

When I tried generamba template install I've got this error message:

/Users/xxx/.rvm/gems/ruby-2.2.2/gems/generamba-0.7.1/lib/generamba/template/processor/template_processor.rb:21:in `install_templates': undefined method `map' for nil:NilClass (NoMethodError)

    from /Users/xxx/.rvm/gems/ruby-2.2.2/bin/ruby_executable_hooks:15:in `<main>'

Actually the error means that there are no templates, and in Rambafile, there are:

### Templates
templates:
#- {name: local_template_name, local: 'absolute/file/path'}
#- {name: remote_template_name, git: 'https://github.com/igrekde/remote_template'}
#- {name: catalog_template_name}

Its ok, but shouldn't it say that there are no templates to install instead of throwing an error?

P.S. None of the provided templates can be used as is.

@appleios thanks for reporting! We'll add a more informative error message.

And the commented templates are not meant to be used in real applications - they are just mark-up examples.
