## rbush

GeoJSON implementation of [RBush][13] spatial index.

### Parameters

*   `maxEntries` **[number][14]** defines the maximum number of entries in a tree node. 9 (used by default) is a
    reasonable choice for most applications. Higher value means faster insertion and slower search, and vice versa. (optional, default `9`)
