I had a quick peek at the .cpp/.h code and have the following tips / remarks.
Check your indentation style to improve readability. (I use notepad++ TextFx plugin, has a good reindenter)
Sequence.h - library for creating timed sequences of code.

void setFuse(int Fuse);
void start(int Steps);
void gotoStep(int StepNum);
unsigned long TimeCurrent;
should both be unsigend long as they hold time derived from millis()
as steps are only positive numbers use an unsigned int (or byte) as datatype
if pause is set to true, and I call start() TimeLast is not initialized.
