which define an arrow between a 'predecessor' trade_state and a
'successor' trade_state, for a given trade_phase_list.
Core concepts in BusinessProcess are the notions of "explanation".
Explanation represents the subtree of a simulation tree of all
simulation movements related to an applied rule, a delivery line,
a delivery, etc.
Example:
portal_simulation/2/sm1/a1/sm2/a2/sm3
portal_simulation/2/sm1/a1/sm2/a2/sm4
explanation(portal_simulation/2/sm1/a1/sm2/a2) is
portal_simulation/2/sm1/a1/sm2/a2/sm3
portal_simulation/2/sm1/a1/sm2/a2/sm4
portal_simulation/2/sm1/a1/sm2
portal_simulation/2/sm1
Business Process completion, dates, etc. are calculated
always in the context of an explanation. Sometimes,
it is necessary to ignore certain business path to evaluate
completion or completion dates. This is very true for Union
Business Processes. This is the concept of Business Path closure,
ie. filtering out all Business Path which are not used in an explanation.
TODO:
- add support to prevent infinite loop. (but beware, this notion has changed
with Union of Business Process, since the loop should be detected only

- should _getPropertyAndCategoryList remain a private method or
become part of IMovement ?
- add security declarations
- why are we using objectValues in some places ?
- add a property to rules in order to determine whether dates
are provided by the rule or by business path. This is an extension
of the idea that root applied rules provide date information.
- use explanation cache more to optimize speed
- DateTime must be extended in ERP5 to support +infinite and -infinite
like floating points do
- support conversions in business path
