genhtml for windows

genhtml.sh

# we need to know the jgenhtml.jar path
# in  this case it's static as we know where is located
# we can handle by running: 
# echo `pwd`/jgenhtml-1.5.jar -> /c/Portables/jgenhtml/jgenhtml-1.5.jar
# and then copy a paste after the `java jar`

java -jar /c/Portables/jgenhtml/jgenhtml-1.5.jar $1 -o coverage/

# the optimal command should look like:
# java -jar ./jgenhtml-1.5.jar $1 -o $2

# get the jgenhtml jar -> https://search.maven.org/search?q=jgenhtml
