[BioC] Bug in marray, indexing single gene in maInd2Coord

[Marcus Davy]

maInd2Coord cannot index a single gene, or vector of length 1.

> L <- new("marrayLayout", maNgr = 4, maNgc = 4, maNsr = 22, maNsc = 24)
 # Index to Coord fails for vector of length 1 (scalar)
>  maInd2Coord(5, L)
Error in "colnames<-"(`*tmp*`, value = c("Grid.R", "Grid.C", "Spot.R",  : 
        attempt to set colnames on object with less than two dimensions

# Index to Coord ok for vector of >1
>  maInd2Coord(5:6, L)
     Grid.R Grid.C Spot.R Spot.C
[1,]      1      1      1      5
[2,]      1      1      1      6
  
>  # Can use a single gene Coord to obtain an index
>  maCoord2Ind(maInd2Coord(5:6, L)[1,,drop=F], L)
[1] 5
