match_to_tree: Match vector of counts to phylogenetic tree
In abdiv: Alpha and Beta Diversity Measures

Match vector of counts to phylogenetic tree

1	match_to_tree(x, tree, x_labels = NULL)

`x`	A vector of species counts.
`tree`	A phylogenetic tree of class `"phylo"`.
`x_labels`	A vector of species labels for `x`.

This function applies a couple of different methods to arrange the data in x to match a phylogenetic tree.

If x_labels is provided, we use this vector to match the elements of x with the tip labels in the tree.
If x_labels is not provided and x is a named vector, we use the names to match the tip labels in the tree.
If x_labels is not provided and x is not named, we assume that x is already in the correct order, check that the length of x matches the number of tips in the tree, and return x.
