### Features

For now, only a few features are implemented:

convert a dgCMatrix or a dsCMatrix to an SFBM, a Sparse Filebacked Big Matrix

compute the product and crossproduct of an SFBM with a vector

solve Ax=b, where A is a symmetric SFBM and b is a vector

A **new compact format** is available, which is useful when non-zero values in columns are contiguous (or almost).
