erb-like template engine

[st0012]

Since go's template engines all need to be compiled, it's not possible to create a template engine that to them. So the only way to have a template engine is to create one with Goby. And I found a simplified implementation of erubis, I think we can try to implement something like this. But we'll need satisfy to some prerequisites before doing this:

• [ ] A CGI-like library
• [ ] Regex class
• [ ] String#gsub, #scan, #empty
• [x] ||= syntactic sugar

FYI: regarding regexp class, I think regexp2 package, which came from .NET Framework code in C#, would be very good for Goby. Very powerful, and the features are almost all equivalent to Ruby's Onigmo and PCRE, except the very-new "absent operator" in Ruby 2.4 as far as I have used.

*Go's standard regexp package is pretty poor :-).

I think at the moment gooby need somehow to provide facility to work with raw bytes. Implementing something like this need more control of the input stream.

@gernest I agree with your opinion, but currently we don't have enough contributors to implement this. Are you interested in implementing this feature?

We're focusing on building API server now, this feature seem to be redundant.
