Fixes #167
Previously the caching in the Language Server created and destroyed a lot of
objects, in particular converting sidecar objects into cache objects, which is
basically the same thing with a little decoration. This object creation/deletion
isn't really needed and causes undue GC stress.
This commit:
needless creation and destruction of objects
originmethod to all cache objects, this commit useshashtable "buckets" to remember which sections and and origins objects should
be categorised as
objects. Instead callers can use the cache directly
although this is not yet enforced
of through the PuppetHelper module. This is easier for testing.
object types and method removals.
Various other maintenance fixes as well.
