Special L1V4 version of libSEDML: update the default version to L1V4

[agarny]

Right now, if you create a new SED-ML document using the special L1V4 version of libSEDML, it will have a level/version of L1V3 while one would expect it to have a level/version of L1V4.

I actually consider it a drop in replacement for the current libSEDML library, As such I figured that the 'current' version (i.e: 3) would be the default. Since the code base will have to do something differently, based on what the software intends to write out, I expected to actively make the decision when creating the SED-ML document, by using the level / version constructor.

if that causes you any issues though, i dont' mind changing that default.

I think it makes sense to default to the 'current' version, but expect users to generally use the level/version constructor if they need a specific version to be used.

Ok, I guess that, at this stage, it makes sense to default to L1V3, but once L1V4 is officially out, I would expect libSEDML to default to L1V4.

[fbergmann]

I totally agree! ... i'll make a full release as soon as l1v4 is out.

again .. if it causes you issues, please let me know and i'll update the default.

Right now, I am explicitly asking libSEDML to create an L1V4 SED-ML document, so I should be fine.
