Don't need *two* older versions of libsbml!
Updates to the testing system.  
* New tests, and a way to test them.
* CMakeLists files updated to include new files, and to reference both .cpp and .h files, so they can be part of the project and therefore searchable.
* Add a way to point to the test files directory.
* Split FBC tests into their own test.
* Add commented-out way of outputting raw data for the sbml.org online validator.
* Better comments for various tests.
* Make test model reactions reversible (since they are).
CMakeLists files updated to include reference both .cpp and .h files, so they can be part of the project and therefore searchable.
add model flattening to SBMLReader
add comp test suite
fix creating selections from SimulateOptions which was read from settings file, resolves #44
remove test code
enable test suite for 950 and 951, warnings are OK
The Windows strtod function is buggy in that it can not parse NaN and Inf, so create a work-around. Resolves #45
toupper fix for clang
Merge remote-tracking branch 'origin/develop' into sys-bio-testing

Conflicts:
	wrappers/C/Testing/Suite_SBML_Tests.cpp
fix for evidently buggy msvc std::copy, resolves #48
Python tester fixes:
* Changed amount/concentration Jacobian test to use the actual SBML file already imported, instead of importing a new one.
* Removed unused import
Make the jacobian model a real python test, and change the tester so that all a testing file needs is an SBML model and some tests.
Merge pull request #51 from sys-bio/develop

Remove completely unused tests, and rename another one that's not yet ready to be tested.  Fix Test_1 so that the 'species concentrations' test is actually working (the '[S1]' format made it think it was a new test.)
