This service manages tools.
Tools can be common, in which case a single instance can be shared by different algorithms, or private in which case it is necessary to specify the parent when requesting it. The parent of a tool can be an algortihm or a Service The environment of a tool is set by using that of the parent. A common tool is considered to belong to the ToolSvc itself.

| StatusCode ToolSvc::finalize | ( | void | ) | [virtual] |
Finalize the service.
Algorithm: 2 passes. First pass:
Inner loop: full loop over all left-over tools + finalize tools with the minimum number of refCounts in the list. + Remove finalized tools from list of tools, and add them to the list of finalized tools, to be deleted at the end. This way, any non-finalized tools who still reference already finalized tools in their finalize() will still find a live tool. Outer loop: keep on going until nothing changes in the list of tools. Checking for: + number of left-over tools + total number of refcounts + minimum number of refcounts

// Several cases need to be covered:
// 1) Simple dependencies: no circular dependencies between tools,
// and tools not using other tools
// 2) Tools-using-tools (but no circular dependencies)
// a) release() is called in the tool::finalize() (e.g. via GaudiAlgorithm)
// b) release() is called in the tool destructor (e.g. via ToolHandle)
// 3) Circular dependencies between tools
// a) release() is called in the tool::finalize() (e.g. via GaudiAlgorithm)
// b) release() is called in the tool destructor (e.g. via ToolHandle)
// 4) In addition to each of the above cases, refCounting of a particular tool
// might not have been done correctly in the code. Typically release()
// is not called, so we are left with a too high refCount.
