Need a volunteer for writing a Range class skeleton (should be relatively easy)

Hello all

I started to port more metadata classes on my local machine, but I'm 
still hitting dependencies. Yesterday I have hit the first dependency 
having a (minor) licensing issue. To be legally safe, I think it would 
be preferable to have a volunteer for providing an initial commit of the 
class described below. I only need the initial commit; from that point 
all subsequent commits were our own. A volunteer could commit that on 
trunk, JDK6 or JDK7 branch at his convenience.

I would like a Range class in the following location:

     sis-utility/src/main/java/org/apache/sis/measure/Range.java

The API of this Range class would be almost identical the the Java 
Advanced Imaging Range class. In fact, this Range class has been added 
in old GeoTools time in replacement to the JAI one, in order to reduce 
JAI dependency:

http://download.java.net/media/jai/javadoc/1.1.3/jai-apidocs/javax/media/jai/util/Range.html

However the initial commit doesn't need to be a fully functional Range 
implementation. In particular, I suggest to omit isEmpty(), subtract, 
equals, hashCode and toString methods since we already have material for 
those methods that we can merge after the initial commit. Javadoc can 
also be omitted except for one or two class introduction sentences.

I have wrote in more details what need to be done there:

     https://svn.apache.org/repos/asf/sis/ip-review/Range.xhtml

Click on the last link ("Range implementation hooked up") - one can see 
a more detailed description of what needs to be done. Peoples 
considering to volunteer should probably not read past the blue line 
with the "Revision 29950" title in it.

We would also need a JUnit RangeTest class, to be written from scratch...

     Regards,

         Martin

Hi, all,

If no one minds, I'll take a look at this one.  I've been neglecting SIS, and this will get me back into the swing of things.

Hey Martin,

If no one beats me to this by mid next week I'll take care of it.

Cheers,
Chris

I should add that there is no rush - there is plenty of other work to do 
in the main time. This is just a wish.
