Separate the endemism scalar and list indices into separate subs

[GoogleCodeExporter]

The endemism analyses (calc_endemism_central and calc_endemism_whole) both
return additional lists to allow exploration of species ranges and weights
used in the calculations.  

These are very useful, but can use large amounts of memory for large data
sets.  

They should be optional rather than default.
