/**  Directions for use:
 **     After including other files, like "encodes.h" and "css_inc.h",
 **     insert the line
 **        #include "extenc.h"
 **     At the end of your source code, inlude the following line
 **        #include "extenc.c"
 **
 **  To encode a floating point number in the data file, your function
 **  should look something like this
 **
 **  void YourFunction(...) {
 **    float x; int y;
 **    ...
 **    encode(YourMarker1);
 **    EncodeFloat(&x);
 **    ...
 **    encode(YourMarker2);
 **    EncodeInt(&y);
 **    ...
 **  }
 **
 **  Encoding an integer looks the same
 **
 **  The encoding of "YourMarker" is optional. But, if you have several
 **  locations in which you are encoding numbers, then this can serve
 **  to differentiate them, (ie, by using different markers before the
 **  float or int is encoded.) To extract the float or int, you can use
 **  the Matlab functions ctx2mat and convint/convfloat.
 **  
 **  Shorts only exist in the 16-bit version of Cortex. (In which case, an
 **  int is 16-bits and a long is 32.) In the 32-bit version, all ints
 **  and longs are 32-bits.
 **
 **  If you want to use the DatawaveEncode function (which tells the
 **  Datawave machine to encode something in its data file) you need to do
 **      #define DATAWAVE
 **      #include "extenc.h"
