Buildfix for mvn compile -P static

[VijayKrishna]

Fixing #44. Two stage change (copying notes from commit notes):

Change to Blinky Util

• Jump was a separate project that I created to factor out some
  grpah related utilites around static analysis. I am now adding
  these utlities to Util so that Blinky does not depend on yet
  another project outside gh/spideruci/blinky.
• I had to modify the compiler setting for Util from 1.7 -> 1.8,
  since I was using a few lambdas in Jump. Added a different task
  to track the work needed to upgrade Blinky to Java 8: see Upgrade all compiler settings from 1.7 -> 1.8 #45
• Testing: Build passing on the following commands:
  mvn clean && mvn compile && mvn test

Change to Blinky Statik

Migrating from Jump to Blinky Util for all Graph related utilites
that were earlier housed in Jump (see gh/vijaykrishna/jump).

Testing: Build passing on the following commands:
mvn clean -P statik
mvn compile -P statik
mvn test -P statik
