Data frames created by the HybRIDS tabulateDetectedBlocks() method now inherit data.frame class and are of HybRIDStable class - this is S3 style class inheritance.
Added method to HybRIDS session object that return the % extent of recombination
Edited recombinationExtent method to be able to give selections of triplets, this selection is passed to the tabulateDetectedBlocks function.
Simplified input of DNA sequences.

Simplified the function - does not try to look up names in global
space, simply checks the class of input variables for DNAbin or
character class attributes.
