Refactored resource-assignment to make it fully Angular compliant
Fixes issue while converting to bpmn xml with ral
Integrated analyser UI into resource assignment to create a complete resource perspective view.
Reorganized code into prspectives package
Introduced the concept of perspective to handle the different perspectives of a model. Reorganised packages to separate core code from model-specific code.
Updating the way prspectives interacts with the RAL Analyser (still unstable). POM versions updated.
