Allowing nested iframes

[thiagodp]

Concordia and its plug-ins support iframes since v1.4.2. However, they are not yet able to refer to nested iframes. Although uncommon, there are some possible uses.

Note: See Issue #55 for named iframes.

Proposal

It could be possible to access nested iframes like this:

...
  When I switch to the iframe <#subframe1> inside <#frame1>
     and I ... # perform some action in the iframe
     ...
     and I switch to the page
     and I ... # perform some action in the page
     ...

Or even like this:

...
  When I switch to the iframe <#subframe3> inside <#subframe2> inside <#frame1>
     and I ... # perform some action in the iframe
     ...
     and I switch to the page
     and I ... # perform some action in the page
     ...

Or using UI Elements:

...
  When I switch to the iframe {Subframe 3} inside {Subframe 2} inside {Frame 1}
     and I ... # perform some action in the iframe
     ...
     and I switch to the page
     and I ... # perform some action in the page
     ...
