profStep-methods: Get and set m/z step for generating profile data

Description

These methods get and set the m/z step for generating profile (matrix) data from raw mass spectral data. Smaller steps yield more precision at the cost of greater memory usage.

Examples

	## Not run: 
# 		library(faahKO)
# 		cdfpath <- system.file("cdf", package = "faahKO")
# 		cdffiles <- list.files(cdfpath, recursive = TRUE, full.names = TRUE)
# 		xset <- xcmsRaw(cdffiles[1])
# 
# 		xset
# 		plotSurf(xset, mass=c(200,500))
# 
# 		profStep(xset)<-0.1 ## decrease the bin size to get better resolution
# 		plotSurf(xset, mass=c(200, 500))
# 		##works nicer on high resolution data.
