Initial commit to query and display indicator values

Total # messages sent by PoC:
sum of archiveQueue.totalTransactions + errorQueue.totalTransactions +
processingQueue.totalTransactions

Total # messages received by HIM:
calculated as # of transactions in transactions_log on specified date.

Values displayed in a simple table for now, and can be filtered by
location(site).
Refine sql queries to display all stats for #17

Shows following stats on reports page (with option to filter by site):
Date
# Sent by PoC
# Received by HIM
# Not Received by HIM
# Processed Successfully
# Not Processsed Successfully (i.e. flagged as 'Processing' or 'Failed')
Add % values for Processed/Not Processed Successfully Indicators
If values are NULL - display 0, not 'None'.
