Extend SolutionParserResult with solution folders information

[gpeto86]

What You Are Seeing?

SolutionParser doesn't parse solution folders.

What is Expected?

SolutionParserResult should contain information about solution folders and the projects they contain.
It would be better if somehow the relationship between solution folders and projects is visible. So it should be more than just another collection property containing a list of solution folders.
Any suggestion?

I have taken a look into the affected code.
Current
SolutionParserResultcontains a readonly collection of SolutionProject (line 42 - link) and SolutionParser explicitly ignores projects with SolutionFolder type (line 76 - link).

Suggestion
A new class would be introduced (SolutionFolder) and it would be inherited from SolutionProject as it's actually is and would have a collection of SolutionProject as child items. SolutionProject would be extended with a Parent property pointing to the SolutionFolder if any.
SolutionParserResult would contain instances of both SolutionProject and SolutionFolder, either in one collection or separately.
