* write test on http://codereview.scilab.org/#change,5671

* check memory leaks

* check what is the faster:
	- From java, send variable [][] and convert into the JNI into variable[][] with row & col size
	- From java, convert from [][] to [] directly and send it to the native code directly (avoid the conversion in the JNI)

* Write documentation

* scilab error management

* if the function fails, .exec() should return false

* check that a java [][] dimensions are consistent
/!\ it can impact performances. 

* move call_scilab.i into the right module (and helper)

* handle of sparse data type
See: http://bugzilla.scilab.org/show_bug.cgi?id=7989

* handle of other data type (list, tlist, mlist)
