Subject: Da steve101 tree reduce (#485)

* Add a tree reduce function to Vec

* Change function names of reduce operation function in Vec

* Change reference to single layer operation in Vec.reduce

* Commint name change for pair macro

* Remove pair, call not necessary and can just be used from grouped(2) and map

* Changed to reduceTree, added default identity function for single reduce.

* Change style of Vec.reduceTree and tests to chisel3 and canonical Scala style

* Cleanup Vec initialization, implicitCompileOptions
