[ENH] Chronology-d-YearMonthWeekRefactoring ( current version ) ( [er][et][su][cd] [BUG] Timespan>>includesAnyOf: doesnot return false )

[tomkoenig at mindspring.com]

Timespan>>includesAnyOf: returns reciever rather than returning false
when no element of the collection is included in the receiver.  The code
reads:
includesAnyOf: aCollection 
	"Answer whether any element of aCollection is included in the receiver"
	aCollection do: [ :elem | (self includes: elem) ifTrue: [^ true]].
A simple test is:
(Timespan starting: DateAndTime epoch duration: 1 day) includesAnyOf:
(Bag with: '07-01-1900' asDate)
