Provide access to parent sections

[meetingcpp]

Basically I'd like boostache to implement this feature from handlebars.js

Currently this leads to a silent error (I don't see an exception, not error logging), only text until the section is printed.

I'm refactoring how the "context" portion works to allow moving back up the data model tree. This is required to properly fix this disabled test: collections2 test

The data (as json) looks like:

{
   "me" :  "Daniel",
    "people" : [ { "name" : "Tom",
                           "job"    : "sweep floors" },
                         {"name" : "Sue",
                           "job"     :"write code"}  ]
}

and the template looks like:

Hi I am {{me}}.
{{# people}}Hi {{me}}, I am {{name}}, I {{job}}.
{{/ people}}

The {{me}} will come from the top context.

Great :)

In which branch does that work?
Would be rather handy to have that...

The newest branch leads only to the out put of: "generic compile for : N5boost9boostache8frontend6stache3ast4rootE"

What is the minimum GCC Version required?
