+ * An almost complete rewrite  of MySpell for use by

+ * 
+ * Special thanks also go to La'szlo' Ne'meth 
+ * <nemethl@gyorsposta.hu> who is the author of the

+
+Appendix:  Understanding Affix Code
+
+
+An affix is either a  prefix or a suffix attached to root words to make 
+other words.
+
+Basically a Prefix or a Suffix is set of AffEntry objects
+which store information about the prefix or suffix along 
+with supporting routines to check if a word has a particular 
+prefix or suffix or a combination.
+
+The structure affentry is defined as follows:
+
+struct affentry
+{
+   unsigned short aflag;    // ID used to represent the affix
+   std::string strip;       // string to strip before adding affix
+   std::string appnd;       // the affix string to add
+   char numconds;           // the number of conditions that must be met
+   char opts;               // flag: aeXPRODUCT- combine both prefix and suffix 
+   char   conds[SETSIZE];   // array which encodes the conditions to be met
+};
+
+
+Here is a suffix borrowed from the en_US.aff file.  This file 
+is whitespace delimited.
+
+SFX D Y 4 
+SFX D   0     e          d
+SFX D   y     ied        [^aeiou]y
+SFX D   0     ed         [^ey]
+SFX D   0     ed         [aeiou]y
+
+This information can be interpreted as follows:
+
+In the first line has 4 fields
+
+Field
+-----
+1     SFX - indicates this is a suffix
+2     D   - is the name of the character flag which represents this suffix
+3     Y   - indicates it can be combined with prefixes (cross product)
+4     4   - indicates that sequence of 4 affentry structures are needed to
+               properly store the affix information
+
+The remaining lines describe the unique information for the 4 SfxEntry 
+objects that make up this affix.  Each line can be interpreted
+as follows: (note fields 1 and 2 are as a check against line 1 info)
+
+Field
+-----
+1     SFX         - indicates this is a suffix
+2     D           - is the name of the character flag for this affix
+3     y           - the string of chars to strip off before adding affix
+                         (a 0 here indicates the NULL string)
+4     ied         - the string of affix characters to add
+5     [^aeiou]y   - the conditions which must be met before the affix
+                    can be applied
+
+Field 5 is interesting.  Since this is a suffix, field 5 tells us that
+there are 2 conditions that must be met.  The first condition is that 
+the next to the last character in the word must *NOT* be any of the 
+following "a", "e", "i", "o" or "u".  The second condition is that
+the last character of the word must end in "y".
+
+So how can we encode this information concisely and be able to 
+test for both conditions in a fast manner?  The answer is found
+but studying the wonderful ispell code of Geoff Kuenning, et.al. 
+(now available under a normal BSD license).
+
+If we set up a conds array of 256 bytes indexed (0 to 255) and access it
+using a character (cast to an unsigned char) of a string, we have 8 bits
+of information we can store about that character.  Specifically we
+could use each bit to say if that character is allowed in any of the 
+last (or first for prefixes) 8 characters of the word.
+
+Basically, each character at one end of the word (up to the number 
+of conditions) is used to index into the conds array and the resulting 
+value found there says whether the that character is valid for a 
+specific character position in the word.  
+
+For prefixes, it does this by setting bit 0 if that char is valid 
+in the first position, bit 1 if valid in the second position, and so on. 
+
+If a bit is not set, then that char is not valid for that postion in the
+word.
+
+If working with suffixes bit 0 is used for the character closest 
+to the front, bit 1 for the next character towards the end, ..., 
+with bit numconds-1 representing the last char at the end of the string. 
+
+Note: since entries in the conds[] are 8 bits, only 8 conditions 
+(read that only 8 character positions) can be examined at one
+end of a word (the beginning for prefixes and the end for suffixes.
+
+So to make this clearer, lets encode the conds array values for the 
+first two affentries for the suffix D described earlier.
+
+
+  For the first affentry:    
+     numconds = 1             (only examine the last character)
+
+     conds['e'] =  (1 << 0)   (the word must end in an E)
+     all others are all 0
+
+  For the second affentry:
+     numconds = 2             (only examine the last two characters)     
+
+     conds[X] = conds[X] | (1 << 0)     (aeiou are not allowed)
+         where X is all characters *but* a, e, i, o, or u
+         
+
+     conds['y'] = (1 << 1)     (the last char must be a y)
+     all other bits for all other entries in the conds array are zero
