#87 Ant task to fail build if coverage less than threshold

[Anonymous]

Something along the lines of:

<taskdef name="check-coverage"

classname="net.sourceforge.emma.ant.CoverageCheckerTask"
classpath="...."/>

<check-coverage report="coverage.xml"
previousResults="old-coverage.xml"
classMinimum="70%"
methodMinimum="80%"
blockMinimum="90%"
lineMinimum="95%" />

Minima would be optional and assume defaults. Minima
are ANDed together.

Options to fail build if coverage declines from a
previous measurement would be nice but not a must-have.
