corrected test for grid names
pairwise and grid names ok
stats named in noKernelMultiGilStats and tested
change circles calc + conc.circle warnings

Change circles calculation to avoid that a single isolated center screw
up everything and to facilitate use of circles if only one center.

Add warnings to conc.circle to avoid this kind of situations
full preAnalysis ok. on one or multiple stats
noKernel working with both preAnalysis and daisyMCMC

also
- reindented
- group even more computations on stats
SynlikExistStats can work with stats(columns) names

no more colNums argument but cols that can be either character (column
names) or numeric (columns number)
indenting and rep declared out of loop to allow debug
added iPartLMoments to the model to allow easy change
