+/**
+ * Useful macros for working with status codes and base::expected.
+ *
+ * These macros facilitate various kinds of strategies for reduction of error-handling-related
+ * boilerplate. They can be can be classified by the following criteria:
+ * - Whether the argument is a standalone status code vs. base::expected (status or value). In the
+ *   latter case, the macro will evaluate to the contained value in the case of success.
+ * - Whether to FATAL or return in response to an error.
+ *   - In the latter case, whether the enclosing function returns a status code or a base::expected.
+ *
+ * The table below summarizes which macro serves which case, based on those criteria:
+ * +--------------------+------------------+------------------------------------------------------+
+ * |     Error response | FATAL            | Early return                                         |
+ * |                    |                  +---------------------------+--------------------------+
+ * | Expression type    |                  | Function returns expected | Function returns status  |
+ * +--------------------+------------------+---------------------------+--------------------------+
+ * | status code        | FATAL_IF_ERROR() | RETURN_IF_ERROR()         | RETURN_STATUS_IF_ERROR() |
+ * +--------------------+------------------+---------------------------+--------------------------+
+ * | expected           | VALUE_OR_FATAL() | VALUE_OR_RETURN()         | VALUE_OR_RETURN_STATUS() |
+ * +--------------------+------------------+---------------------------+--------------------------+
+ *
+ * All macros expect that:
+ * - The error type and value value type are movable.
+ * - The macro argument can be assigned to a variable using `auto x = (exp)`.
+ * - The expression errorIsOk(e) for the error type evaluatea to a bool which is true iff the
+ *   status is considered success.
+ * - The expression errorToString(e) for a given error type evaluated to a std::string containing a
+ *   human-readable version of the status.

 It is sometimes convenient to use an intermediate frame when dealing with

-The Drift / Bias Compensator blocks serve two purposes:
-
-- Compensate for floating reference axes by applying a high-pass filter, which
-  slowly pulls the pose toward identity.
-- Establish the reference frame for the poses by having the ability to set the
-  current pose as the reference for future poses (recentering). Effectively,

 The stillness detector blocks detect when their incoming pose stream has been
 stable for a given amount of time (allowing for a configurable amount of error).
