[vinayg-usc]

• [ ] Pipeline to capture data from a WebGL build for at least one metric

For singleton implementation: https://github.com/vinayg-usc/alter-ego-game/pull/29/files#diff-c1d1fda8b501948af8dfed8ab1a790d9002e4aa372c48d6f747be91a1a17c1a4

Todos Till Friday for Analytics:

@smaransrao : ** Highest Priority 1. Saving data during WebGL build(google forms or anything else you want) instead of local save

2. Plotting data on graphs that is exported

@Ashutosh-30 :

1. Creating objects in a way that analytics doesn't reset when level reloads.
2. Add functions for easy hook installations.
