Subject: [PATCH] Revise Travis-CI configuration to enable scipy

The default Travis-CI system image does not include scipy, so including it in requirements.txt will yield a build error. The current workaround employs miniconda to install both numpy and scipy, as referenced in travis-ci/travis-ci#2650. An alternate approach is proposed in travis-ci/travis-ci#2638.
