Start implementing SLA violation algorithm
Add JUnit Tests for Violation algorithm
Small changes
Remove comment
Merge branch 'slaViolations' into visualization
Remove old TODOs
elastictyManager: Change to service

Change from manually instatied class to service.
Move costs calcualtion to datacenter
Track costs and work around sla list bug
elastitcyManager: Fix costs unit

Costs are tracked per hour so use that as unit for the x value
Dump costs JSON to files

Use GSON to convert the cost lists to json and write them out to temp
files.
Track and save total costs as well
Add HTML5 based visualizer

Add a HTML5 script that takes the 3 files as input and renders a chart using
them as input (minute / costs in $).
Style fixes
SLA Violation algorithm
Memory part
Add cpus and bandwidth
Move sla violation algorithm in new class
Add comment
Add todo: Threshold parameter
visualization: Do not create total costs data

This can be computed from the sla and energy data when generating
the graph.
