Application programming interface for the RSE Services Layer.

## Package Specification

The RSE Services layer provides interfaces and basic utility classes for remote operations. There is no restriction whatsoever about the kind of those operations, and actually there isn't even a need for remote systems to be involved. The Services defined here provide basic functionality for RSE to operate on.

The RSE Services layer is designed to have only minimal dependency into Eclipse core APIs, such that Services can eventually be re-used in environments outside Eclipse. This can be done today by providing a library with mock objects for the few Eclipse interfaces that Services currently use: `IAdaptable`, `IProgressMonitor`, `IStatus`, `NLS`, `PlatformObject` and few others related to the Eclipse Extension Registry, which are only used in the Activator and can thus be replaced easily by a different mechanisms for providing extensions.
