Generates tooltip for plot.

1	beam_tooltip(hv, plot_info, plot_data, plot_type, tt_content, tt_range = 5)

`hv`	Hoover.
`plot_info`	chosen mapping from the `data` object from the output of `ggplot_build` for displayed plot.
`plot_data`	data on which the ggplot is based
`plot_type`	Type of plot corresponding to the data from first mapping. Accepts either `'geom_point'`, `'geom_segment'` or `'geom_col'`. Default `'geom_point'`.
`tt_content`	Optional. If `NULL` in the tooltip will be displayed names of columns with corresponding values from data. One can customize tooltip content adding parameter `tt_content` here. It should be a list of `chosen_cols` and `row_text`. To display some values from the data in the content one should reference to the relevant column from the `chosen_cols` and in `row_text` write appropriate type of that variable like in the function `sprintf` (for example `'%s'` in case when chosen variable is a character string).
`tt_range`	A number denoting maximum distance between hoover and objects on the plot. The row, whose distance to the hoover is less than `tt_range` will be selected from the whole data. Default 5.
