As a programmer, I need to link up the WifiDirect singleton to the chatview so that two way communication code is actually being executed.

[Madministrator]

Acceptance Criteria:

• The chat fragment calls WifiDirect.sendInMemeoryFile() to send data
• The chat fragment needs to properly package text messages and files into InMemoryFiles
• The chat fragment needs to save messages to the database prior to sending the data.
