correct tabulation error for failure and assert reporting
update Reporter interface to require name at end
adding JunitReporter

working on #6; not done yet
adding description property to MatchResult

now using message for info about failure
adding timings to test execution (working on #6)

the jUnit schema expects units of seconds. We are able to provide that
at millisecond precision with Platform.getTime(), but this is still not
fine-grained enough to catch the duration of a typical single test.
moving ReporterManager from models package to reporters
un-'fixing' the tabulation error fix; use MatchResult.description
using result.message when available for errors
move type matching into helper functions
provide description and error message when not a container
updating the read me for v1.1.0 and adding a screenshot
ignoring junit xml reports
