Added row operators.  Needs more unit tests
Competed tests for multiply and add
Update test_row_operators.clj
some tests passing - need to fix multiple and add, then write integration tests
[Issue 40] jdowns Add elementary row operations
doc edit
Merge branch 'master' into develop
separate benchmarking and rendering of results

also, add functions to dump/load benchmarking results
better benchmarking code, more benchmarks
add color encoding to benchmarks
cleanup
refactor benchmarking suite to a separate file
more benchmarks
ndarray is now the default implementation
fix default zero value for sparse-map numeric matrices and vectors
fix #58: default equality check should return true iff dims are same
Merge branch 'develop' of github.com:mikera/matrix-api into develop
make equality test actually be runned as a part of compliance suite
add tests for method existence

it is known that if someone implement some protocol only partially,
clojure does not complain. this test will break in such situation.
Added row operation protocols
