Anne-Laure did most of the work to add more informative messages when
root finding for event detection fails. This commit adds a few polishes.
- Added Anne-Laure Lugan as a contributor
- Updated messages to print g values to full precision.
- Made try {} as small as possible since catch() is so broad
- Fix checkstyle warnings
- Add test to check message is formatted correctly

This occurs in very rare cases due to numerical noise.

Fixes #743

Previously, when a RESET_* event caused two other event detectors to
trigger simultaneously and discontinuously at the same time then an
infinite loop would occur in acceptStep as it tries to backup up and
process the one event before the other, but the even time remains the
same. This affects all propagators.

Now tryAdvance allows the other event to occur first if the events are
simultaneous.

Also fixes some cases where tryAdvance returns false (indicating the
other event should occur) but does not update t0. This erroneously
searched for events before the first occuring event if it was as
RESET_*. I.e. events could have occured out of chronological order.

Also fixed a bug in CloseEventsTest that caused two events to be
simultaneous when they should have been different by 1 ulp.

An archive for sources can be downloaded
directly from Gitlab, in pages related to
tags or releases.

Previously the test test of the compiler plugin was not compiled. Now it
is compiled and run.

There are just too many use of the default data context in the tests,
and they are intentional: tests finds their data by just configuring the
default data context, not by implementing a dedicated context.
