new feature: MODELKIT SPACEGROUP "123" or MODELKIT SPACEGROUP 123
 -- allows setting of the space group after loading
 -- accepts any name of a space group accepted by the spacegroup()
function or a number from 1 to 230
 -- note that some space group names have extensions:  "6:a", "6:b",
"6:c". If these are given
    simply as "6" or the number 6, then one of these options will be
used.
 -- will not set the space group if the current unit cell is not
appropriate for the given space group
 -- can accept semicolon-separated Jones-Faithful operation listing:
"x,y,z;-x,-y,-z"
    which can be obtained for any space group by:

    x = spaceGroup("6:c").spaceGroupInfo.operationsXYZ.join(";")

    or for the current space group by

    x = _M.symmetryOperations.join(";")

 -- using operation lists is recommended over using names, as this
covers all possible space groups
    and avoids any ambiguity in settings

new feature: MODELKIT SPACEGROUP "123" packed
 -- also packs the unit cell after assigning the space group

new feature: MODELKIT PACKED
 -- packs the unit cell

new feature: MODELKIT ADD {xxx} PACKED
 -- packs the unit cell just for the specified subset of atoms

new feature: x = spacegroup("123") or spacegroup(123)
 -- returns a map containing keys:
	    HallSymbol
		HermannMauguinSymbol
		crystalClass
		ita
		itaFull
		operationCount
		operationsXYZ
 -- note that some space group names have extensions:  "6:a", "6:b",
"6:c". If these are given
    simply as "6" or the number 6, then one of these options will be
delivered.
 -- if a space group name is given that is not recognized, such as "6:d"
or "400", "?" will be returned.

new feature: x = spacegroup("x,y,z;-x,y,z")
 -- similar to spacegroup("123") but finds the space group with this set
of operations

new feature: x = spacegroup("x,y,z&-x,y,z") or
spacegroup("&x,y,z;-x,y,z") or spacegroup("x,y,z;-x,y,z&")
 -- use of "&" instead of ";" or adding "&" at the beginning or end of
the string
 -- gives an array of space group names for space groups that have AT
LEAST these operators, maybe more
 -- for example:

	$ print spacegroup("-x,-y,-z;-x,y,z;-x,-y,z;x,y,-z;-x,-y,-z;-x,-y,z;-y,-x,z+1/2&").format("JSON")

	[ "131","226" ]

new feature: x = spacegroup(6, [a, b, c, alpha, beta, gamma])
 -- adding an array of unit cell parameters can sometimes help in
distinguishing among space group settings,
    at least for simple cases where the setting is dependent upon the
"unique" axis

new feature: x = spacegroup("x,y,z;-x,y,z", [a, b, c, alpha, beta,
gamma])
 -- adding an array of unit cell parameters to an operator list will
ensure that the returned space group
    is consistent with the given unit cell. For example,

		$ print spaceGroup("&x,y+1/2,z+1/2", [5,5,5,90,90,90]).count
		64

		$ print spaceGroup("&x,y+1/2,z+1/2", [5,5,6,90,90,90]).count
		50

		$ print spaceGroup("&x,y+1/2,z+1/2", [5,5,6,90,90,120]).count
		0

    because the second case does not include 14 matching cubic groups,
and there are no hexaganol groups with this operation.
