Instagram refactoring 

1. Changed function names to clarify functionality
2. Modified jsdocs in some areas to show return results 
3. Trim Response:
   - modified to return an array instead of entire response object
   - removed lodash chaining
4. Sort By Distance:
   - Modified inputs so it operates on array returned by Trim Response instead of results.data
   - added lodash chaining
5. Distance Between (Note: Changed function name to distance): 
   - Changed argument input to take 2 objects, each containing a longitude and latitude for the first and second location instead of 4 arguments
   - changed spacing & variable names for readability & style guide requirements
6. dayInMilliSeconds: 
   - removed function since this is always a fixed value and replaced with a variable assigned to that value
   - variable is not currently used , may want to remove this
