Reworked examples. Searching for optimal lambda.
Begginning working on waggle digits challenge.
Renamed alpha to lambda where appropriate
Reordered and renamed several methods
Experimenting with goc for vector operations.
Go implementation:

BenchmarkDist2    100000             18380 ns/op
BenchmarkLeastSquare     2000000               840 ns/op

C implementation:

BenchmarkDist2    200000             10788 ns/op
BenchmarkLeastSquare     2000000               968 ns/op
Profiling digits sample
Added old implementation for easier comparison if needed.
