Checks if a partial ranking is preserved in the ranking induced by `scores`

.

```
is_preserved(P, scores)
```

`P` |
A partial ranking as matrix object calculated with neighborhood_inclusion or positional_dominance. |

`scores` |
Numeric vector containing the scores of a centrality index. |

In order for a score vector to preserve a partial ranking, the following
condition must be fulfilled:
`P[u,v]==1 & scores[i]<=scores[j]`

.

Logical scaler whether `scores`

preserves the relations in `P`

.

```
library(igraph)
# standard measures of centrality preserve the neighborhood inclusion preorder
data("dbces11")
P <- neighborhood_inclusion(dbces11)
is_preserved(P, degree(dbces11))
is_preserved(P, betweenness(dbces11))
is_preserved(P, closeness(dbces11))
```
