lengthscale parameters for scaling isotropic versions

ported calib functions over to package with documentation
and examples

added first pass at vignette


1.1-1 (02 Sept 2014)

avoid re-calulating derivative info when optimizing over
the nugget

moved several Suggests to Depends for R CHECK

submitted rays paper and added to references

now beta ray-based search including option to control the
number of rays

now outputting close in object to inspect fidelity of
search


1.1 (20 March 2014)
---
