SparseVector (#140)

Browse Source 
* Add SparseVector

temp

* Add gtest

* Some reworking of the sparse concept

* Change type of M from int to size_t

* Add const modifier

* Add needed declaration for accessing elements of _indices

* Add norm_squared, norm, longerThan

* Add test for all sparse vector functions

* Add missing const to slice's norm_squared, norm and longerThan

* Construction from Vector<M> and carray[N]

* try to fix ci
