.PD
This function takes an arrayref of events as the first argument. All additional
arguments must either be a package name, or a regex. Any event that is
generated by a tool in any of the package, or by a tool that matches any of the
regexes, will be returned in an arrayref.
.ie n .IP "$grouped = group_events($events)" 4
.el .IP "\f(CW$grouped\fR = group_events($events)" 4
.IX Item "$grouped = group_events($events)"
This function iterates all the events in the argument arrayref and splits them
into groups. The resulting data structure is:
.Sp
.Vb 1
\& { PACKAGE => { SUBNAME => [ $EVENT1, $EVENT2, ... }}
.Ve
.Sp
If the package of an event is not known it will be put into and arrayref under
the '_\|_NA_\|_' key at the root of the structure. If a sub name is not known it
will typically go under the '_\|_ANON_\|_' key in under the package name.
.Sp
In addition there is an '_\|_ALL_\|_' key under each package which stores all of
the events sorted into that group.
.Sp

\& \*(Aq_\|_NA_\|_\*(Aq => [ $event\->[3] ],
\& \*(AqTest2::Tools::Basic\*(Aq => {

\& plan => [ $events\->[0] ],

.ie n .IP "$arrayref = facets \s-1TYPE\s0 => $events" 4
.el .IP "\f(CW$arrayref\fR = facets \s-1TYPE\s0 => \f(CW$events\fR" 4
.IX Item "$arrayref = facets TYPE => $events"
This function will compile a list of all facets of the specified type that are
found in the arrayref of events. If the facet has a \f(CW\*(C`Test2::EventFacet::TYPE\*(C'\fR
package available then the facet will be constructed into an instance of the
class, otherwise it is left as a hashref. Facet Order is preserved.
