Fixes #868

Fixed #864

This adds support for dimension retrieval and yield feature between
providers.

Fixes #856

Fixes #862

These containers are intended as replacements for HashMap when the
number of keys is very small (such as in spacecraft states).

They have smaller overhead, are more debugger-friendly (when dealing
with additional states and derivatives), and all in-place
incrementation.

The new interfaces StackableAdder and IntegrableAdder allow to build
state incrementally according to some dependency order if some adders
require additional states or derivatives computed by other adders.

Fixes #853

FieldParameterDrivenDateIntervalDetector.

Fixes #848

These classes streamline several ways to trigger maneuvers.

Fixes #717

Previously it would fail, now event detection will work, albeit with
some errors due to #834.

Fixes #798

Also remove Propagator.DEFAULT_LAW. Use IntertialProvider.of(Frame)
instead. See discussion on !189. Part of #586.

Previously when an analytic propagator handled a continue event the
first part of the step would be passed to the OrekitStepHandler twice.
Now it is only passed once. Seems to have been present when
AbstractAnalyticalPropagator was created, about a decade ago, and not
detected in all the changes since then, so I guess no one uses that
combination much.

Previously when there was a step handler analytic propagators were
forced to take small steps though EventDetector and OrekitStepHandler
can both use large steps. Removed this unnecessary restriction to
improve performance.

Fix #830

Previously a null reset state behaved as CONTINUE with analytic
propagators but not with integrated propagators. This was an
undocumented "feature". Removed it to be consistent.

Previously ClasspathCrawler matched the whole path against supported
names which caused problems with ^ as other loaders only matched the
file name. Added a test case.

Implemented for all analytic and the GlONASS propagator. The DSST and
Numerical propagator do not have a frame available in their constructor,
so the new behavior could not be implemented. Aligning the attitude
frame with the propagation frame speeds up propagation when the user
does not care about attitude and it many cases it removes a dependence
on the default data context.

Fix #586

It now has better performance when the attitude is aligned with the
propagation reference frame by avoiding multiplying by zero. With
analytic propagators using this attitude provider instead of the default
has been observed to result in a speed up of 2 in some cases, e.g. with
the TLEPropagator.

For #586

Improve exception messages with AbsoluteDates by including the duration
between the dates. Many messages updated, some new messages added.
