#Function to find frame dimensions when a window is to be sectioned into nrow rows and ncol columns:

##Input:
## nrow: number of rows in plot
## ncol: number of columns in plot

##Output:
# a list giving the left, right, bottom and top dimensions for each of the nrow*ncol frames to be made in plot

##Required by:
### plotAllele
### plotChrom
### plotGenome
### plotSample
### plotFreq
### plotHeat
### plotWeightedFreq 


##Requires:
### none
