/**
* Shadow cache is a facade that covers all the operations with shadows.
* It takes care of splitting the operations between repository and resource, merging the data back,
* handling the errors and generally controlling the process.
*
* The two principal classes that do the operations are:
* ResourceObjectConvertor: executes operations on resource
* ShadowManager: executes operations in the repository
*
* Note: These three classes were refactored recently. But it will need more refactoring.
* It is not a very pretty OO code. But it is better than before.
