"static" / local storage on stack

Link to original bugzilla bug (#615)
the static keyword appears several times in the tutorial
with a static float
Internally, a fixed-size Eigen matrix is just a plain static array
since Eigen will try to allocate the array as a static array
the author may want to express if a variable is defined in the scope of function, the allocation / deallocation on the stack will cost almost nothing.
However, it may lead to confusion since static has its special meaning in C/C++ language.
