version conversions

mapping from rubygems like versions to maven version ranges. the maven version ranges uses following interval:

( is start boundary excluding the boundery
[ is start boundary including the boundery
) is end boundary excluding the boundery
] is end boundary including the boundery

the conversion leaves maven version ranges as they are, i.e. the conversion is idempotent.

ruby	maven
-- empty --	[0,)
!2.3.4	(2.3.4,)
=2.3.4	[2.3.4,2.3.4.0.0.0.0.1)
~>1.8.2	[1.8.2,1.8.99999]
~>1.8	[1.8,1.99999]
>1.2	(1.2,)
<1.2	[0,1.2)
>=1.2	[1.2,)
<=1.2	[0,1.2]
>=1.2, <2.0	[1.2,2.0)
>=1.2, <=2.0	[1.2,2.0]
>1.2, <2.0	(1.2,2.0)
>1.2, <=2.0	(1.2,2.0]

Important a version without operator like 1.2.3 will be a maven version, i.e. not a maven version range.
