First major commit which :
incorporates 1) an adjacency matrix, 2) constrains for leaf
distributions <= maxareas and 3) several outputs are proposed when batch
testing root constraints;
resolves 1) a superdouble library precision bug for big trees (approx.
5000 taxa) and 2) corrects for the root priors in BioGeoTree::reverse.
implemented an adjacency matrix per time period
improved testing of range connectivity: using BGL
cleaning up...and learning Git the hard way
optimised P matrix exponentiation and surrounding code
Alloperipatric speciation now available only for weakly connected range
components
implemented DIVA style vicariance (cf. Ronquist & Sanmartin 2011,
Fig.4a)
