Add comments to .travis.yml.
Create README.md
Fix Travis badge.
Delete old ReadMe.txt.

Supplanted by the new README.md.
Assertion in debug was being thrown for mass properties of ground body with zero mass (property) and non-zero inertia. Eventhough it does not affect the system, the properties are inconsistent so made the inertia property all zeros to be consistent. Tests case now passes in debug.
Address compiler warning "/arch:SSE2 unrecognized. SSE2" on VS and CL_64 by removing compiler line option in CMake when compiler is CL_64.
For GCC/Clang, always set GCC_INST_SET.
With GCC/Clang, use O3 instead of O2.

The tests take the same time to run either way.
No longer specify sse2 by default.
Install g++-4.8 even when compiling with Clang.

This is so that Clang can have a newer libstdc++; without it, Simbody's tests will fail.
Remove liblas from travis

liblas-dev was a typo; I meant to put libblas-dev. This is unneeded though, b/c liblapack-dev will install libblas-dev as a dependency.
Fix compilation errors for SIMM translator due to changes in Model API.
CMake: Remove reference to obsolete cmake variable USE_LIBRARIES_FROM_REPOSITORY
Merge pull request #5 from chrisdembia/update-travis

Allow .travis.yml. to enable Travis builds and test runs.
Build Java and python wrapping in travis.

This requires installing swig in travis.
Upgrade lepton.

I updated lepton to the version at
https://github.com/SimTk/openmm@373c3878348383f19068444f24d56525489b3063.

This version of lepton gets rid of a warning message that Clang was giving.
Do not unroll loops in gcc/Clang

I copied @sherm1's changes at https://github.com/simbody/simbody/commit/a834ea26c59bb8bfd5b672034ce32bfe2069d321
Re-enable loop unrolling.
Merge pull request #11 from opensim-org/Issue-9

Address compiler warning "/arch:SSE2 unrecognized. SSE2" on VS and CL_64...
Split up testCMC* into multiple tests.

This allows us to run the tests substantially faster when multiple cores are
available. In particular, this will make the travis tests run quicker.
