nutrientRange: Geneate nutrient range stats
In MattForsyth/oceanchemistry: Ocean Chemistry Analysis

This function produces nutrient ranges at two different depths - usually at the surface and at depth. The depths are given to the function as two separate depth ranges. The result of nutrientRange is stored under nutrientRanges in the global environment.

1	nutrientRange(depth_column, nutrient_columns, depth1, depth2, depth3, depth4)

`depth_column`	The depth (or pressure) values.
`nutrient_columns`	All nutrient data. Must be provided in separate columns.
`depth1`	The upper limit of your shallow depth range.
`depth2`	The lower limit of your shallow depth range.
`depth3`	The upper limit of your deep depth range.
`depth4`	The lower limit of your deep depth range.
