Consider changing name of getMarkers()

[Charl-Hutchings]

I'm just wondering whether it would be worth changing the name of the getMarkers function?

I use this function frequently, but not only to pull a table of markers. For example, the function is also useful for pulling a table of classification results by specifying the necessary fData column in fcol = . Since you can pull a table of any fData column, perhaps the function should be named to reflect this.
