sandpit 0.2.0

A garbage collected arena
Documentation

VERSION 0.3.0 - Alloc Blocks into Regions - Add more bench tests - Add A Fuzzing Test suite - fix GcError todos! - Defragmentation - switch to major during minor collection - grow, shrink, and layout alloc options

VERSION 0.2.0 - #[derive(TraceLeaf)] - Mutation Input and Output - tracer channels - add GcConfig - free large objects - Trigger yield from space/time limits - using derives inside of /src

ISSUES - Better Config - add allocator config? - easy swap allocator? - editing config while gc is running? - review the trace and traceleaf derives - they dont work for a lot of types, things like unit/unamed structs - add a lot more trace impls - Mutator Context? - the presence of a GcPtr, GcArray, or Mutator all indicate we are in a mutator context - add non blocking versions of the gc mutate functions?
