Makefile

##
# Provides targets to build, test and run the Namespace Browser application.
#
# make  # Builds the project.
# make test  # Runs unit and integration tests.
# make start  # Starts the services and http server needed to run the application at http://localhost:9001
# make clean  # Deleted all build, testing and other artifacts.
#
# Note: :; at the beginning of commands is a work-around for an issue in MacOS version of GNU `make` where
# `make` may not invoke shell to run a command if command is deemed simple enough causing environment variables
# like PATH that are modified here not to be used.
# :; tricks make to assume command is not simple and needs to invoke shell.
# see http://stackoverflow.com/questions/21708839/problems-setting-path-in-makefile for details.
