get a slice from a specific column

Synopsis
getcolslice(columnname, blc, trc, incr, startrow, nrow, rowincr)

Description
A slice from the entire column (or part of it) is returned. Warning: it might be big!
In blc and trc -1 can be used to indicate all values for a dimension (-1 in blc is equivalent to 1, so -1 is especially useful for trc). Note that blc and trc should not contain the row number, only the blc and trc of the arrays in the column.

		Allowed:	String
blc	in	Bottom left corner (e.g. [1,1,1] is start of 3D array)
		Allowed:	Vector of Ints
trc	in	Top right corner
		Allowed:	Vector of Ints
incr	in	Stride (defaults to 1 for all axes)
		Allowed:	Vector of Ints
startrow	in	First row to read (default 1)
		Allowed:	Int
nrow	in	Number of rows to read (default -1 means till the end)

		Allowed:	Int
