/*
* This set of routines was written primarily for the compseq program.
* Feel free to use it for anything you want.
*
* compseq counts the frequency of n-mers (or words) in a sequence.
*
* The easiest way to do this was to make a big ajulong array
* to hold the counts of each type of word.
*
* I needed a way of converting a sequence word into an integer so that I
* could increment the appropriate element of the array.
* (embNmerNuc2int and embNmerProt2int)
*
* I also needed a way of converting an integer back to a short sequence
* so that I could display the word.
* (embNmerInt2nuc and embNmerInt2prot)
*
* embNmerGetNoElements returns the number of elements required to store the
* results.
* In other words it is the number of possible words of size n.
