+/** Simple data logger using local flash memory.
+ *  Every start it creates a new file LOGnn.TXT, where nn stands for number of files.
+ *  Counting files on /local is based on an example code of LocalFileSystem class.
+ *  Every msg will be saved on a new line.
+ *

+ *
+ *  Example:
+ *  @code
+ *  #include "mbed.h"
+ *  #include "logger.h"
+ *  
+ *  Logger logg();
+ *  char bfr[127];
+ *  
+ *  int i=1;
+ *  char ch='L';
+ *  float f=1.1;
+ *
+ *  int main(){
+ *      logg.open();
+ *      sprintf(bfr,"format your msg as you wish, %d,%c,%f",i,ch,f);
+ *      logg.save(bfr);
+ *      logg.close();
+ *  }
