artdaq Release Notes 1.07.00 (22-Apr-2014)

This version of artdaq is the continuation of the development that was being released in the v1_05_xx series. It continues to use the v1_08_10 version of art. The jump to version v1_07_00 was needed so that we could provide a fixed version of the artdaq code with a newer version of art for the NOvA DDT (that version was released as artdaq v1_06_00).
