Create the floodlight adapter module, it's a prototype.
Add rest api service for OmniUI, it's a prototype
	- /wm/switch/json
	- /wm/link/json
	- /wm/port/json
Add Resource files, which handle the query from restapi.
	- LinkResource
	- PortResource
	- SwitchResource

Add 3 datatype for switch,port,link.
	- SwtichInfo.java
	- PortInfo.java
	- LinkInfo.java

All of them are prototype.
Add a READEME for floodlight adapter module
In order to conflict to floodlight's LinkInfo.
Change the LinkInfo to LinkInfoForOmniUI
	1.create class member for link infomation
	2.override the serialize way
Change the LinkInfo to LinkInfoForOmniUI
Modify the LinkResource.java
	1.get the link infomation from ILinkDiscoverySerivice
	2.check the link and add to the result list

Use  "curl -s http://localhost:8080/wm/omniui/link/json/" to test its
functionality and it works.
Remove PortInfo and combine it into SwitchInfo.
We won't provide any service for the other java module.
So remove the related functions.
-Modify READEME.md
-Rename READEME.md to README.md
Delete the query of port information /port/json
Add the port info in switch query.
SwitchInfo:
	1.Use OFPortStatistics  type to store the port's information.
	2.Serialize the port's info
		portNumber
		recvPackets
		recvBytes
		transmitPackets
		transmitBytes
1.Use thread to query switch's information(port... etc) for each
2.Use SwitchInfo to store the switch information (dpid, flow table,
		ports)
Complete switch's query;
	- dpid
	- flow entry
		- flow actions
	- ports
SwitchResource:
	Use a thread to query info info
SwitchInfo:
	Serialize switch info to json.
1.Add a python script to test the adapter's function
2.The script will use the restAPI to query the infomation and output
with JSON format
Fix some presentation error
First version of Web UI
Remove redundancy message
Fix scrolling of #rightcolumn
Add sorting to flow/port table
