Travis build time analysis tools

Usage:

# fetch builds from Travis
$ ./get-travis-builds.py --limit=2 > builds.json

# merge multiple build JSON files into a single file
$ ./merge-travis-builds.py builds.json other-builds.json > merged-builds.json

# generate HTML plot locally; can be exported to plotly for sharing
$ ./plotter.py builds.json

The --limit parameter limits the number of requests when pulling builds from Travis (get-travis-builds.py). Each request pulls about 25 builds. In 2016 --limit=400 pulled about a year's worth of builds.

All scripts have command-line options; use --help or -h for more details.
