A data.frame of all available layers in the bcmaps package.
available_layers()A data.frame of layers, with titles, and a shortcut_function column
denoting whether or not a shortcut function exists that can be used to return the
layer. If TRUE, the name of the shortcut function is the same as the layer_name.
A value of FALSE in this column means the layer is available via get_data() but
there is no shortcut function for it.
A value of FALSE in the local column means that the layer is not stored in the
scotmaps package but will be downloaded from the internet and cached
on your hard drive.
