Scenario Measures: Slow loading due to watchers

[perryr16]

Issue

In my test data I have 10 audits each with 4-38 scenarios each with a single measure. I am noticing a large number of watchers associated with the ui-grid. With that data, I get ~130,000 watchers on the inventory detail page and it takes about 60 seconds before the measure ui-grid becomes visible.

Proposed Solution

• utilize angular ui-grid features like fastWatch and flatEntityAccess to speed up UI-grid load times
• Only render scenario ui-grids when a user expands a scenario.

Benchmarking

Tested with a property that has 8 scenarios, 6 of which have 1-3 measures (10 measures total).

Description	Number of Watchers
Current implementation	4200
Removing the scenarios and measures section	500
Proposed Solution	850
