Calculate and assign a GBIF-style degree cell id and centi-degree (0.1
degrees, dividing a 1 degree cell into 100 centi-degree cells) cell id to each
record. This function also creates a custom grid scale if parameter gridscale
is supplied. This is a necessary previous step for some functions like
mapgrid
Usage
getcellid(indf, gridscale = 0)
Arguments

input data frame containing biodiversity data set
gridscale
generate custom grid scale column for mapping. Default is 0.
