v0.11.6

Added a algorithms::resiliency module to with a spectral_gap function.
Expanded the ability to get adjacency matrices with new Graph methods:

• get_adjacency_matrix_vec
• get_adjacency_matrix_vec_vec
• get_adjacency_matrix_nalgebra
• get_adjacency_matrix_ndarray
• get_adjacency_matrix_sprs

To use the nalgebra, ndarray or sprs methods you must enable the "adjacency_matrix" feature in Cargo.toml:
graphrs = { version = "x.y.z", features = ["adjacency_matrix"] }
