/**
* Simplified deployement framework designed for hot deployement of endpoints and media components.
*
* Deployement is represented by tree of folders. Each folder may contains one or more deployement descriptors. The most
* top deployment directory is referenced as root. Maindeployer creates recursively HDScanner for root and each nested
* directoty. The HDScanner corresponding to the root directory is triggered periodicaly by local timer and in it order
* starts nested scanners recursively.
