Rename the example jacoco.xml file to be jacoco.xml.in to stop CMake
from apptempting to calculate Jacoco Coverage when running over itself.
Enclose a push of -1 to the coverage vector to only happen if there is a
fin to calculate for. This prevents a crash if the target file doesn't
exist.
Add the ability to parse the XML output of the Jacoco tool.
Jacoco (www.eclemma.org/jacoco) is a Java coverage tool.
Add and integrate a class for the parser and
include a test which utilizes the new parser.
