Get variable data (double type)

Reads data from a netCDF variable with array slicing support.

Parameters

[in]	var	Variable handle
[in]	start	Start indices for each dimension
[in]	cnt	Count of elements to read for each dimension
[in]	stride	Stride (interval) for each dimension
[in]	imap	Memory mapping vector (see NetCDF manual NF_PUT_VARM_type)
[in]	siz	Size of val array
[out]	val	Array to store read data
[out]	iostat	I/O status (NF90_NOERR on success)
