Added the Three Variable option to the 2/3 Variable Graph

[derekagorhom]

Fixes partly #7260 This is ready for review I have done A-F, currently working on G-I For the name changes, they need to be done on the database before the titleof the dialogue and the by option can be changed.

[derekagorhom]

I have done items G- I for the item where we implement the facet when the multi selector is single, apparently for the dialogue to produce results for the first value it must remain in the multi selector, so what i did was add a condition that if the values in the multi selector is more that one, the facet option will be disabled. i will have a meeting with antoine during tomorrows general meeting to see a way around this problem. @rdstern this is ready for review

@jkmusyoka you have been quiet on whether you agree on this. I hope these messages are getting through?

@rdstern , @fran2or , Below are the combinations for the 3 variable graphs. can i know which graphs should be available for which combinations.

@derekagorhom Below are my initial thoughts on your query and hence there should be discussion before they are included in the code. What are your thoughts @rdstern, @jkmusyoka, @lilyclements and anyone else that can contribute?
