Name : fifoWrite.
Description : Function to add a char to the buffer.
: \note Before calling this function, user is responsable for checking in a loop if provided buffer is not full.
: \example
while( fifoFull(buffer) );
fifoWrite(buffer,'c');
Argument(s) : Pointer to a fifoType buffer, character to add
Return value : 0 - success; 1 - Buffer Full.
