update view to get all test/result data from the suite

[kellyredding]

Before the view gathered its data partially from the suite and partially processed it on its own. This would break if the suite implements custom ways of storing and making data available.

This reworks the views and view helpers to get all data from the suite and updates the default suite to implement all suite behavior by storing data in memory and processing it in memory.

This is prep for assert-sqlite where its suite will not store data in memory but will instead store it in the db and query the db for data processing.

There are a few other tweaks I've added here:

• added output to the result api and handling - it is needed by the views and should have been added originally
• switched from array count to array size - supposedly it is faster: https://github.com/JuanitoFatas/fast-ruby#arraylength-vs-arraysize-vs-arraycount-code
• removed a bunch of view helpers that are seemingly not used. They may have been for kellyredding/assert-view-leftright and kellyredding/assert-view-testunit - both of which are deprecated.
• shortened the "reverse_*" api methods for less typing

@jcredding ready for review.

@kellyredding - Very nice, looks good :boom: Interesting about count vs size.
