Add more linear algebra tests

Fix a small bug in the .inv() method. While .inv() returned the correct
inverse, it did so with an additional column at index '-1'. Although the
other functions in the library ignored the '-1' column, the additional
column prevented equality comparisons. This has been fixed.

Fix bug in gauss_elimination and add tests

Add tests for gaussian elimination function. Tests uncovered a bug; for
matricies of dimension greater than 3, the results of gauss_elimination
would always fail because of a problem in the back-substitution portion
of the algorithm. Bug has been fixed.

Prevent overflow error in centralF pdf

Use the algorithm found in the R source to calculate the centralF pdf,
which avoids large exponentiation and hence doesn't suffer from NaN
overflow errors.

Temporarily use vows URL in package.json

Update to the epsilon() API was introduced, but no planned release date
for the change. To accomidate that the remote URL for the tar.gz has
been used in order to manually pull down latest master.

This commit SHOULD be reverted as soon as vows has released an update.
