Util.MutateParameter now uses mutationDelta with interpolation objects
cleanup nonused target parameter to mutateParameter
made helper util function for interpolating values
+ some test cleanup
adding interpolation to mutaeConnectionWeights
fix tests not being linted
tests pass again
added grunt-sloc to build
+ cleanup build tasks
more grunt task cleanup
fix not copying interpolationType on connection clone correctly
mutateNodeParameters mutationRate now affected by mutationDistance
fixed parameterDefaults not being defaulted correctly when extending node
fix mutation deltas not being negative
no need to copy parameter mutation chance
nodes now mutate based on interpolation
connectableParams now has a new object def
use new object def for connectableParams
added mutation info to connections in toJSON
split out mutateParam function and added sanity test
better checking on weightedSelection
can now state chance of each mutation type
