Currently, there isn't a lot of documentation explaining what callsites
and registration are for, and how they work. There's some documentation
explaining this stuff, but it's all on the register_callsite method,
rather than in the callsite module itself. We should fix that.

This branch adds new documentation to tracing-core's callsite
module. Hopefully this should shine some light on how this part of
tracing works.

# 0.1.27 (June 7, 2022)

This release of `tracing-core` introduces a new `DefaultCallsite` type,
which can be used by instrumentation crates rather than implementing
their own callsite types. Using `DefaultCallsite` may offer reduced
overhead from callsite registration.

### Added

- `DefaultCallsite`, a pre-written `Callsite` implementation for use in
  instrumentation crates ([#2083])
- `ValueSet::len` and `Record::len` methods returning the number of
  fields in a `ValueSet` or `Record` ([#2152])

### Changed

- Replaced `lazy_static` dependency with `once_cell` ([#2147])

### Documented

- Added documentation to the `callsite` module ([#2088], [#2149])

Thanks to new contributors @jamesmunns and @james7132 for contributing
to this release!
