A sparse matrix index

This is a convenience trait to enable using various integer sizes for sparse matrix indices.

Required methods

`fn index(self) -> usize`

Convert to usize.

Panics

If the integer cannot be represented as an usize, eg negative numbers.

`fn try_index(self) -> Option<usize>`

Try convert to usize.

`fn index_unchecked(self) -> usize`

Convert to usize without checking for overflows.

`fn from_usize(ind: usize) -> Self`

Convert from usize.

Panics

If the input overflows the index type.

`fn try_from_usize(ind: usize) -> Option<Self>`

Try convert from usize.

`fn from_usize_unchecked(ind: usize) -> Self`

Convert from usize without checking for overflows.
