TASK 1 - sessions

Sessions were implemented by creating a new "Session" entity
	With both a data model (a sub-class of ndb.model)
	And a request/ response model
	Data types for the models:
		Date for date.
		Integer for start time so it can be sorted numerically (24hr).
		Integer for the data id since it creates/ stores integer ids for each entity.
		The rest are strings since they could contain any kind of characters.
		(Also included computed property - for the query problem (task 3b)).


The following endpoints were created for sessions:
	1. createSession - creates a new session using the SessionForm model
	2. getConferenceSessions - returns all sessions for specified conference
	3. getConferenceSessionsByType - returns all sessions by type WITHIN a specified conference
	4. getSessionsBySpeaker - returns all sessions by speaker name ACROSS all conferences

Endpoints utilize additional methods:
	1. _createSessionObject - creates a new session entity from the request
	2. _copySessionToForm - copies the data into the response object

TASK 2 - Session Wishlist

implemented two new endpoints:
	1. session/wishlist/{key} - to add or remove a session from user's wishlist
	2. session/wishlist/ - to return all sessions in that user's wishlist

TASK 3a - Additional Queries

implemented two additional queries as new endpoints:
	1. getConferencesByCity - specify a city and get all the conferences taking place there
	2. getConferencesBySeatsAvailable - returns conferences with at least that number of seats available

TASK 3b - Query Problem

QUERY: How to query for all non-workshops before 7pm?
PROBLEM: An inequality filter can only be applied to ONE property
SOLUTION: 
	Use ndb.ComputedProperty to create a new property in the model of the two inequality filters
	Then query for if that property is true

TASK 4 - Add a Task

implemented a set_featured_speaker task
checks for more than 1 session for that speaker, 
and adds to memcache as featured speaker.
this task is added to the queue each time a session is added

added a getFeaturedSpeaker endpoint method to return the
featured speaker from memcache

RUNNING THE APPLICATION

1. Create a new google developers application at console.developers.google.com
	a. Copy the application name to the first line in app.yaml
	b. Create new oauth 2.0 credentials (APIs & auth -> Credentials)
	c. Copy the client ID to the replace the client ID in the following files of the application:
		1. settings.py
		2. static/js/app.js (to enable the front end)
2. Navigate to http://[application-name].appspot.com/_ah/api/explorer
	a. Run getProfile first to add your google account to the data
	b. Now run the different endpoints from the API explorer or
	c. Interact with the front-end application at http://[application-name].appspot.com/
