coalescent Code

Tex file coalescent_theory.tex added with the aim of documenting theoretical progress; it didn`t work in the end.

Netbeans SE project "coalescent" created. Note that "nbproject" sub folder was not checked in, didn`t know about that until later.

The recursion for infinite alleles is implemented, it is tested successfully by the table from Hein`s book.

Initial import of the project. This commit only creates the folder on the repository.
